Great beading surface, beads don't roll away, comfy to work on. 11 x 14 inches. Dark colour is good for light colour beads - will probably never show dirt but will show cat hair. Unless you have a dark cat. Can't be specific as to what colour it will be exactly. Some mats are actually a different colour on each side. Bonus! (Hence the apparently light pink one in the photo.)
By the each.
