Those who knit or crochet know this to be an accurate definition of YARN: An item to which the word "enough" does not apply. This is a handmade ceramic mug created by me in my New Jersey studio. Handmade from bone china clay, this mug measures 4 x 4 and holds 16 oz. The exterior is white, and the interior is black. Created with all lead free, non toxic materials- safe to place in the dishwasher and microwave. Great gift for a maker who knits or crochets- and remember it's not hoarding if you have plans for those skeins and balls!
