Kinda like shoes! I love taking a class where I can learn a technique that makes me buy the new foot. Collect 'em all, as they say on those commercials for kids. LOL Just got the circle attachment after seeing Libby Lehman demonstrate (also I'll be taking a 5 day class w/her at Asilomar), NEEDED the pintuck foot (or 2!) after watching Ricky demonstrate his cording technique. For me, it's just great fun.
I'm here in "about to get our first real snowfall and it'll be a whopper" Michigan, hoping to escape tomorrow to Orlando (meeting, not Mickey).
