I am sure everyone needs these, the hard ones wear out eventually and can sometimes cost a lot for what they are. Fabric ones can be washed, they use up those odd bits of fabric and they are quite quick and easy to make. This also got me thinking they would be quite nice to put in a little gift hamper for a tea loving friend, a nice cup, some coasters, good tea and some nice biscuits. If these were presented carefully in a covered box it would be better than the overpriced hamper style gifts that will be hitting the shops soon.
First of all you can use a regular coaster that you have already to cut your squares of fabric to size, I am going to bind these around the edges so cut exactly the size you want. I am doing three layers, one is denim, but it depends on the thickness of your fabric.
