1. Create the Background + Transfer the Pattern

Start with 12 pieces of background fabric, trimmed down to 20” wide by 18” tall. Using thread that matches the background, sew the fabric together in groups of three along the short edge.

Once it’s all sewn together, press the entire background fabric. Then you’re ready to transfer the design!

Because you’re transferring the pattern onto a large background, you’ll need to create a poster board compass to make it easier. With that, you can transfer your pattern onto the background fabric, as shown in the video.

Cut your different colored fabric into 4” bias strips. (Your pattern tells you how many strips you need for each color.)

2. Appliqué the Rainbow Arcs

After all of your strips are ready to go, topstitch the arcs to the background. Latifah goes over some quilting options to help you finish your rainbow throw. She also demonstrates using bias tape appliqué for improv quilts and adding a 90-degree angled turn in your bias tape.

For an arc with two colors, join the strips with a straight seam. Measure to double-check that the resulting strip is long enough for the arc. Using a 2" (50mm) bias-tape maker, press strip into 2" bias-tape . Repeat with all remaining arcs.

Good to Know

There are two different types of joins used in the bias tape rainbow. You'll use a diagonal join when making the bias tape, because it allows the same amount of stretch all along your tape. You'll use a straight-line join when connecting one color of tape to another within your rainbow arcs, to create that bold color shift.

Starting with the smallest arc, stitch the inside of the curve to the background fabric, as shown in the video. Press and stretch the bias tape so the outside edge relaxes. Sew the outside edge, topstitching very close to the edge of the bias tape. Press and stretch again until the bias tape lies flat.

Repeat with all the arcs. Trim the bias tape so it’s even with the edge of the background fabric. Check your quilt top measurements and square up if needed.

3. Quilt Your Top

Allover quilting looks great in this design, so don’t be afraid to quilt right over the bias tape — doing so will actually help stabilize the quilt and hold everything together.

As for your binding, do what looks best to you! We used a ¼” binding that matches the background fabric exactly, so the rainbow arcs really pop.

Pro Tip

If you send your quit top out to a long-armer, remember your batting and backing needs about 4-5” of clearance on all sides. Double-check that this meets their requirements before shipping.

Free-motion quilting can feel intimidating when you're first getting started. After all, you're used to a walking foot doing the hard work of guiding your design. But once you switch to that darning foot, the power is in your hands. And that's a good thing!
