I am probably a little slow. I admit it. It just never occurred to me that I could buy that stretchy stuff that little girl's headbands are made of by the yard. It is usually less than a dollar a yard depending on where you look. A yard makes about two headbands depending on the age and size of the child.
I bought a yard of a couple of colors at my local Hobby Lobby and went about making my headbands. What should have taken minutes took me almost an hour, so here, learn from my mistakes.
1. Measure you child's head according to how you want it to fit. You might want it a bit smaller than your child's head because they are stretchy and you don't want it falling off. You decide.
2. When you go to sew them, fold it in half with the right sides together and then sew a straight seam close to the edge. Seriously, put the right sides together and sew across the side that doesn't have so many frills. I didn't do this and I ended up unjamming my machine for 45 minutes.
The are really easy and so much cheaper than buying them pre-made.
