The boy's belts started breaking so I wanted to get them some similar to what I had as a kid. I think mine were rainbow pattern or something. The problem is I didn't ever see them in Wally World and I don't go shopping very often in other places so . . .
in the Sewing dept of Wally World I picked up some Nylon strap by the yard and some D-rings.
I got 1 yard cut for each belt - about 84 cents. Then a package of D-rings was 88 cents for enough to make 2 belts.
I sewed them and melted the other end with a flame to keep it from fraying and Wha-la . . . inexpensive belts in a variety of colors.
If I were to do it again, I think I would go to a craft store with a bigger variety of nylon strap. These work just fine, but I might choose a heavier, thicker strap if I had a choice.
P.S. "Wally World" is my affectionate name for Walmart.
