Kathryn- I was thinking of doing something like that but was worried the "slice" would eventually pull apart. I have some Gorilla Glue which is strong but not sure how it would hold up with repeated stepping.
Pam- The bubbles are pretty large and crackle/pop when I'm using the step which gets annoying. I haven't tripped yet but if they get much larger, it could happen.
Julie- That sounds like a good option to start with...at least it will eliminate the annoying popping.
Thanks Ladies!
