As far as I could figure out in the many discussion about tile is that the Fabrico markers and Sharpie markers are interchangable - so if you are doing tumbled tile then you could stamp with staz-on - heat set image - color with Fabrico or Sharpies - bake and viola....
I have done the glossy 2x2 tiles (~3 in a sheet of 36 at Lowes and Home Depot) and stamped using Stazon - heat set - colored with sharpies and viola...
I went looking for the tumbled tile yesterday at Home Depot and found they had 2 different styles availabel at mine - it looked like 6-8 in a pack for about ~$6. I didn't buy any because I need to force myself to finish up some other project first...
after reading some articles (go to google and type in stamping on tumbled tiles) I am going to follow the advice here - stamp with Staz-on - heat set - color with my Sharpies (went to Wal-mart and picked up the earth-tone set - now I have all the colors and my husband christened me Queen of the Loons) - bake for 20 minutes - add some cork to the back and for under $10 I should have 2 sets of coasters to give for gifts
