Homemade Coasters: Shelf Liner Backing

I see a lot of people online making their own coasters, which I have done for a year or so now myself.  I have run the gamut in things I have used as backing, but my favorite is the shelf liner that feels like a silicone web.

You can find it at Wal-Mart for a VERY fair price.  One roll will go a very long way. 

I stick it right on with E6000, of course.

Felt is rather frustrating, those little felt pads are EXPENSIVE, and all of it just about needs E6000 anyway to stay on.

Best benefit of shelf liner? Perfectly slice-able with your handy dandy paper cutter (thanks Xacto for another quality product!).

Happy crafting!
