I got my supplies at JoAnn's Fabrics (love the teacher discount and 40% coupons!) Bag of approx. 77 glass tiles, E6000 glue, and button magnets about $13.00 before discounts. I read other blogs about laminating and how bad they turned out - but they were using modge podge. I decided to try the laminated paper with E6000 glue and it worked perfectly. This whole project did not take me very long at all - about an hour.
