Install a Truly Invisible Zipper: Pattern Match With Glue Basting
By Sherri Sylvester
Installing an invisible zipper
in your project is a simple way to get a professional finish, but what if you could make the zipper seam disappear, too? Take a few simple steps to match the pattern across your zipper opening and it becomes almost invisible as well. It's easier than you think!
Follow these simple steps (and grab your glue stick!) to get a perfect pattern match across your zipper opening.
The thought of using a regular school glue stick to baste fabric might surprise you, but it is one of my most-used sewing tools
! The best glue stick I have found is Elmer's X-treme School Glue Stick. A regular strength glue stick works well too, though the bond is not as strong. As long as the glue is applied with a thin, even stroke and is fully dry before sewing, it does not leave residue on your machine needle.
I am using a simple sleeveless bodice with a center-back zipper in this tutorial. You can also use this tutorial to match fabric across any straight zipper opening. It could be on a skirt, dress back, side zipper or even a throw pillow cover.
Preparing your fabric
This tutorial augments the instructions you have in your sewing pattern. You may need extra yardage to match your fabric. You can also find a general tutorial on how to install an invisible zipper in the Bluprint blog post “Sewing an Invisible Zipper in 10 Easy Steps
.”
Step 1:
Place and cut the left pattern piece. Keep in mind, you will need enough fabric elsewhere in your yardage to be able to cut a matching piece for the right side. Note: Trace, then cut, the pattern piece for a more accurate match.
Step 2:
Cut out the left pattern piece. Draw the seam allowance line (on the right side of the fabric) and press it under along the seam line.
Step 3:
Place the left pattern piece on your uncut fabric, paying attention to grain lines. Use the folded zipper edge to find the matching area for the right pattern piece.
Step 4:
Place the right pattern piece so the seam allowance is under the left piece and zipper seam line is matched up. Cut out the right pattern piece.
Step 5:
Draw the seam allowance line (on the right side of the fabric) and press it under along the seam line. Lay the folded zipper seam line edges together to check that both sides of the zipper seam match along the folded edge. Adjust if necessary.
Sewing the invisible zipper
Step 6:
Unzip your zipper and press the zipper tape coils open gently. Line up the edge of the left zipper teeth with the marked seam line on the left pattern piece. Glue, hand or machine baste your zipper in place between the dots marked from your pattern piece.
Step 7:
Stitch the basted zipper as close to the coils as possible using a zipper foot or an invisible zipper foot.
Zip up the zipper and press the seam gently to flatten the fold beside the zipper coils. Place the right folded edge up against the left side zipper seam. Check to make sure the left seam and folded right edges match. If not, re-press the right fold until they match.
This step took me about 5 minutes of pressing and re-pressing to get a perfect match. In the end my final fold was about 1/16" different than the original fold — about the width of the tailor's chalk seam allowance line I drew.
With the zipper still closed, use a glue stick to apply glue onto the unsewn zipper tape. Press the folded seam allowance onto the zipper tape, matching the fabric pattern across the zipper opening. This is easiest if glue basted in small increments — about 2" at a time — until the fabric is basted to the entire zipper edge. (If the glue does not hold right away or dry quickly, press it gently with a medium-heat iron to dry it faster and get a secure hold.)
Zip up the zipper, press gently to flatten the seams and check your matching pattern. It if is not close enough, remove your stitching and try again. If the zipper tape/coils are showing you may need to stitch the seam again, closer to the zipper coils.
Check your matching pattern
Enjoy your perfectly matching zipper! Now you can finish the rest of your project according to the pattern.instructions.

Pattern grading is an easy way to replicate a pattern to scale, saving you from having to draft the whole thing. It can be your go-to if you need to size an entire pattern up a smidge. (Though you shouldn't try to go more than two sizes up or down, as that would disrupt the balance of the pattern.) There are a couple different ways to pattern grade, but let's focus on two of the most common methods.
For kids who want to sew — but may not be ready for a sharp needle or complex sewing machine — this personalized piece of wall decor is a great starter project. Not only will they be proud to gift it or hang it in their room, but working the stitches helps them practice an even, repeating pattern that builds fine motor skills. It's a win all around!
Clothing and accessories are an awesome way for kids — and everyone, really — to express their creativity. But instead of buying new stuff, help your little fashionistas upgrade what they've got with some cool DIY felt patches. They're easy to make and look great ironed on everything from backpacks to jean jackets.
Given all the uncertainty swirling about COVID-19, there's a lot of desire to help. While the Centers for Disease Control and Prevention say staying home, washing your hands and practicing social distancing are some of the best things to do at this time, they're also encouraging everyone wear a cloth face cover when out in public.
Truth: there's nothing fun about having your skirt cling to your body. Not only can it feel uncomfortable, but it also prevents the skirt from hanging as intended. But with a simple handmade slip you designed yourself, you can rock any skirt with style — meaning this old classic just became a wardrobe must-have once more.
Whether you're lounging on the weekend or working from home, there's nothing better than a great-fitting pair of yoga pants (aka leggings) to make your day-to-day more comfy. Here's what you need to know to sew a pair — or five.
You love browsing, buying and using sewing patterns. And while making patterns may seem like a job for the pros, there's actually one pattern any home sewer can — and definitely should —make. It’s called a sloper, and it's basically a generic pattern based on your measurements without any wiggle room, seam allowances or style. It's the building block of all patterns, helping you to not only sew clothes, but design them.
Truth: a shower curtain can make or break your bathroom. If you're revamping your space (or moving into a new place altogether), this simple DIY can save you hours of searching for that perfect patterned curtain. And there's no need to install grommets or special hardware — this curtain can be made using only your sewing machine.
Buttons are so much more than closures — they're also a way to tie your piece together and give it a flawless finishing touch. While these little additions can seem intimidating at first, with this step-by-step tutorial you'll have them fastened on in no time.
Bias tape is a great way to bind, or seal in, raw edges. And while it’s commonly used as quilt binding, you can actually incorporate it into a variety of projects, whether you need to sew a face mask or want to add a fun design element to a garment. Here’s how to create the durable, stretchy tape — even if you don’t have a bias tape maker on hand.
Selvages run the entire length of a fabric bolt, and many people consider them to be garbage, cutting them off and throwing away without a second thought. But this finished end of your fabric can be handy in a project. After all, it's so tightly woven you don't have to worry about fraying. Here are some tips for putting 'em to good use.
Picture this: you go to the fabric store, pick out the perfect materials for your next project, and come home only to realize that — doh — you already have great fabric you could have used tucked away in a forgotten corner of your sewing room.
If you're a quilter or sewist, you've probably come across bias tape before. And while it's commonly used for quilt binding, there are a ton of ways you can incorporate bias tape into any project. The best part, though, may be just how easy it is to make yourself.
Ruching is when fabric is gathered along a seam to provide decoration or fullness. You may have seen it before on sheers (like in the skirt pictured above) or swimsuits, but there are so many opportunities for ruching in patternmaking. The technique looks particularly great on a fitted garment, where it accentuates your body's curves.
Apparently, sometimes we creative types think rather differently than the rest of the world. But we're all in the making game together — so whether you're a newbie sewist or a master of the craft, we bet you can't help nodding along to these truths only sewers understand.
When you're making a statement in a vintage-style dress, you need to have a petticoat. It's just a fact. Petticoats can turn a simple A-line dress into a real stunner — just check out the image below.
Fitting can be a challenge for even the most seasoned garment sewers. But that's where a moulage, or "mold," fitting system comes in. It was developed and used in couture houses to reduce client fitting times, yet home sewers can use the technique to draft personal slopers for a blouse, dress, jacket or an overcoat.
If you're under 5'4", you're considered a size petite by the fashion industry — as well as the pattern companies industry. And when you're searching for a pattern, you want one that helps you look taller and gives great proportions to flatter your shape. Keep these tips in mind while you're browsing to help you find the perfect pattern for your next garment.
When fitting a sewing pattern, you typically check standard measurements such as the bust, waist and hip — all measurements of circumference. But there's another that's critical to getting the perfect fit: vertical dimension. This measurement isn't usually marked on most patterns, but you should measure and adjust your patterns for it (in both dimensions, actually) to get the fit you need — especially if you're plus-size or full-busted.
If you're going to sew your own clothes — or even alter store-bought ones — you have to know how to hem. The good news is it's a super easy skill to pick up, as the bottom edge is simply turned up and stitched into place. (Things get more complicated when dealing with extras like lining, a kick pleat or a cuff.) The method below can be used whether you're hemming a dress, a pair of pants, a skirt, a sleeve — anything you put your mind to!
Getting the fit just right is one of the most challenging parts of sewing clothes, mostly because the process isn't a singular step. Rather, it begins before the first pattern piece is even cut, and continues throughout your sewing.
