I generally make rectangular quilts for beds and cribs, but lately I've been making a few large square quilts for throws, think about 70" x70". I like this size for throws. It's big enough that both little daughters and I can curl up under it, and it's a great size for their 'tents'! My DH is six foot and the 70x70 size never seems to bother him at all. Both shapes of quilts have their uses.
