This is my first effort to make a coaster. I I used a felt type stabilizer, the fabric I stitched on was felt, and I use a white vynal table cloth fabric on the back. I put the vynal so that the soft backing side was on the outside. I had to use a black permanent marking pen on the outside edges as the white was showing through. I think next time I'll use a tearaway instead of a cutaway stabilizer. The design is from Embroidery Library's Graceful Dogs collection.
