There is one true fact about mosaic tiles...they are definitely in the eye of the beholder!
The list of potential tiles is endless but some examples include: traditional china and stained glass tiles, commercial ceramic tiles, glass gem cabochons, seaglass, driftwood, polymer clay tiles, jewelry findings, glass beads, glass shapes, 3d objects, half-cups and half-saucers, pebbles, commercial stone tiles, polished gemstones, handmade clay tiles and just about anything else that can be glued down and grouted.
Here are some really cool retro flower power mugs and plates that I found for my next mosaic project.

Can you imagine the possibilities with these awesome tiles? I'm thinking of mosaicing a large lamp base with these tiles. Yes, I really do want a retro flower power lamp!
Glass shapes! Try flowers, dogs, cats, ladybugs, whales, dolphins, butterflies...whatever you find appealing. These are so versatile. You can either incorporate these into your mosaic projects or attach them to the surface of a mosaic.
Go 3D and try some handmade ceramic tiles! These are so versatile. They are waterproof and can used in backsplashes, shower enclosures and other areas where moisture is present.

Other items that I have used in my mosaics include wine corks, resin stones and bottle caps (not pictured).
You don't have to spend a fortune to make mosaics! Go to thrift stores and junkyards...you will be amazed at the many items that you run across that will spark your imagination and creation of a unique mosaic!
Just be sure to use the appropriate base for your mosaic tiles. Most surfaces work best indoors although there are surfaces that can withstand outdoor temperatures and other weather conditions.
