I made some ON toddler flops for my daughter last year and had a HORRIBLE time as well. I tried everything i could think of to get the korkers to stick. I even tried sewing them through the straps...which didn't work. lol Eventually I ended up doing ribbon loops and a clip on the korkers. It was really a pain. I just got her 2 new pairs out today to start working on and I thought "This is going to be fun..." I'm so glad I wasn't the only one that had trouble with the toddler ones!! (.../sorry you had trouble as well. lol) Here's hoping they aren't as much trouble as they were last year!!
