I found this idea here...and I thought these would be perfect for when my kids are riding their bikes ...or for when we go camping and hiking this summer! I just bought my ribbon at Walmart...and the rubber O-Rings I bought at Home Depot. They came in a pack of 10. I couldn't find the same size that they suggested here...so I ended up getting 1 1/16" x 7/8" x 3/32" and that worked too. I used a little Fray Check on the ends of the ribbon...folded the ribbon a couple of times...stitched...and I was done! Soooo EaSy!! For complete instructions on how they made theirs ... click HERE!
