hot glue gun
Step 1: Cut a rectangle out of your fabric. For my bow that ended up being about 3" long and 2" wide (at the widest part), I cut my rectangle to be 3.5"x6". If you want a bigger bow, cut a bigger rectangle.
Turn the rectangle right side out and press with the iron. Slip stitch the opening closed.
Fold it in half hotdog style and sew along the long end so you have a narrow tube.
Turn the tube right side out and press the seam to the back.
I didn't like how wide this made the strip, so I folded it in half and kept it in that position by putting a strip of hot glue in the crease. I'm sure there's a better way to do it, but I just went with the flow.
Try a couple different numbers of folds to see what you like. Then pinch in the center.
Wrap the strip around, putting hot glue under it as you go. If you're wanting to attach this to a older girl's headband, you can glue the headband under the narrow strip as you go. When you get back to where you started, trim off the excess. I didn't like the raw edge, so I did a tight and narrow zigzag along it.
Finally glue it in place!
You're done with the cutest bow ever!
Now, you can attach it to whatever you want to embellish, I wanted another headband for Ada, so I whipped up one of my t-shirt headbands and hot glued the bow to it. Viola!
Doesn't she look cute?!
