When my mom passed away I "inherited" several boxes of 3" blocks all cut out of heavy polyester. I put them together, selecting the colors so that they looked pretty and made a BUNCH of quilt tops. I made one into a car quilt for my grandson for graduation and he promptly put it on his bed. He LOVES it! He knows he can use it at the house, at the beach, in the car, wherever and grandma won't be upset to see it there. I put a light batting in it and backed it with a sheet. It was heavy but that's what he liked about it. I have enough blocks made for several more quilts, just need to dig it out and get with the program. They are really worth the effort!
