I've visited more thrift shops in the past six months than I have in 20 years!
I've collected quite a few pieces of china, glass, etc. and my husband is starting to call me a "hoarder".
Robin, I found my first tiles/china on Art Fire
http://www.artfire.com/ and Etsy
http://www.etsy.com/ under "Craft Supplies". Their prices are fairly reasonable and you can get some pretty nice assortments and shipping isn't too bad. There are plenty of mosaic suppliers on the web too and if you sign up for their newsletters you can take advantage of the sales they have.
