Cut a 3-inch wide strip from each bandana using scissors and a ruler. This part is really easy to do with a rotary cutter, if you happen to have one.
You'll end up with three strips for each headband. Fold one end of each strip to make a "W" shape.
Stack all of the strips together and place one end of the elastic in the middle; sew through the end.
Braid the fabric together until the headband is long enough to fit around the head. Trim the elastic with scissors.
Sew (or glue) the trimmed end of elastic to the other end of the headband as you did before.
Notes
Step 3: It doesn't necessarily matter the order of your strip colors, as they are all going to be braided together. I wouldn't worry about it.It was really easy for me to just hold the pieces; pinning would've taken too long! Or maybe I'm just impatient. Either way, use pins if you need to.And here's the best part if you're looking for a no-sew option. Simply glue it all together with a hot glue gun and glue sticks, one layer at a time.Step 4: Make the braid looser if you want a bigger/thicker headband, and tighter if you want a smaller/skinnier headband. I loosely tied the elastic around the back of a chair to keep everything steady while I braided.
