I attended a great session by Maria Vennekins at Tangle U. Maria travelled from the Nertherlands to attend Tangle U as a learner and to offer this elective class. I was lucky to get in as it was a small class. She modeled this after seeing decorated books made by chinese women to keep their sewing supplies in. She adjusted the measurements and designed a kit that holds pens, tiles, reference cards and bijou tiles.  So handy and beautiful.
