Stamp a Rainbow Onto a Plain T-Shirt in a Single Afternoon

We all have "blah" T-shirts that wind up rumpled and never worn. So we're on a mission to rescue those tees from the back of the closet — all it takes is punch of color! This rainbow cutie is definitely a hit with kids, but grownups can totally get in on the action, too.

What you'll need:

  • Plain T-shirt
  • Paper + pen
  • Thick cording or thin rope
  • Scissors
  • Clear plastic lids
  • Hot glue gun
  • Fabric ink stamp pads in rainbow colors

Step 1: Make the rainbow template

Let's draw the rainbow! Except to start, it can be in black and white. Draw one arch for every color ink you have on a small sheet of paper.

Step 2: Cut the cording

We'll need to cut a piece of cording for every line on the rainbow. Start with the biggest: Drape the cording over the line, and cut it to size. Repeat until you have a cord for every color.

Step 3: Glue the stamps

Now, we'll make a stamp for each line (this is the easiest way to get bright, unmuddled colors). Place a clear plastic lid — aka the base of your stamp — over the template you drew earlier. Trace one of the lines with a hot glue gun, then put the corresponding cord in place. Keep going so you have one stamp for every line.

Step 4: Stamp, stamp, stamp!

Use a fabric-safe stamp pad to ink up the cording on the biggest stamp. Press the stamp firmly on your shirt, and follow it with the remaining colors. You can make as many rainbows as you like — the more, the brighter!
