I love yo-yo's. When I was about 10 years old, my friend and I made a bulging shoebox of them. I'll bet it got lost over the years. My mother (85) still lives in the same house, so perchance it may be hidden somewhere there, but I doubt it. What I'd give for them now! I love your finished project. Try to just reinforce the ones that come loose, and treat it gently. It's beautiful! Sara
