These coasters are all made by John in his workshop in TN.  Each one is handcrafted, so there will be small variations in size and design.  This is normal with these types of products - if you are expecting them to be identical, they won't be - the differences in pattern and wood are intended!  

Some of the wood types used:  cherry, maple, walnut, white oak, purpleheart, yellowheart, and padauk.
