I don't use mine. I mainly design on the string (wire). I don't even clip the end, I string onto the spool, crimp one end, then cut and crimp the other. Unless it's a design that I am working from focal out. Once in a GREAT while, I will dig out the flocked board.
Saw a lap desk at Michaels a few days ago, which had one on top...looked kewl! and "carryable".
