I've been a busy girl over the last few days as I have 2 table sales next week and I needed some different stock. I've made three sets of 4 coasters and have 20 more coasters that I bought today to do too.
They are 4inch square white ceramic tiles topped with a 3.5 inch square of scrapbook paper and topped with 3 coats of mod podge to make them durable. I will then add felt to the back to stop them scratching the table. Hopefully they will sell well.
