I have two kids here that LOVE to dip their cookies in their milk, got that habit from their father!! I decided they needed special coasters to keep the milk drips off the table.
I used the Some Odd Girl stamp Set Cookies N Milk. You have to admit that these are super cute! I stamped the images on natural, tumbled times that I got from Lowe's. Because they are VERY porous you can never be certain how the colors will look but I think these two tiles colored up pretty good. I also used acrylic sealer so the tiles are safe from liquid spills.
On a side note...I prefer my cookies and milk separate!
