Long-arm? I think that's such a funny name!
Ok, so how do you go about figuring out which kind to get? I took my first lesson at the LQS last night on their long-arm. It's computerized but I don't think all long-arms are computerized, are they? I had so much fun I'm going back on Sunday to quilt a "real" top instead of a practice one! Although if I put a cute border and binding on my practice one it'd be a pretty nice throw!
