OK I'm stumped. They have about every other kind of measurement of grids except a 10.5! I asked a woman at JoAnns if she knew of anyone that carried them, she said they don't make them!! Can anyone tell me why? I thought about asking my ex-brother in law to cut me one from plexyglass and smoothing the edges. It's awkward having to use the 9.5 and 12.5 all the time. I mean, isn't 10.5 a popular square anyway... or am I just still new and don't know what I'm talking about! Thats probably it but...well you know. Had to ask. :mrgreen:
