I'm afraid that if I make them too small it will be mostly colored hexes and not so much pattern - which isn't necessarily bad, just not near as much fun! And at this point bigger is better also because it would go together faster, and I'd like to at least get the top done in the next couple weeks. I've gone as small as 2 1/2", but never bigger than 4" -- but I've never worked with a print this large either... it's intimidating me (naughty fabric, I'll show it in the end!)
