Quilted navy and green tartan coasters - set of 4 (Black Watch)

We use coasters all the time in our house and I was getting annoyed with the condensation on the outside of my G and T glass making the coaster "stick" to the bittom of my glass!!! So, decided to make some quilted coasters that would absorb this small annoyance for ourselves. 

Set of 4 Quilted cotton coasters/mug rugs
navy and green tartan s - (Black Watch)
100% Cotton wadding to help absorb any drips
