Well, I have done some quilt TOPS in a day...but a whole quilt? HA HA HA HA hahahahahahahaaaaaaaaaaaaa!!!!!!!!!!!!
Have to say, tho', some are definitely quicker than others - and like quiltinlee said, especially when done by someone else! LOL
I just remembered, I DID do a quilt in a day once....but it was only postcard-sized. It WAS quilted too...does that count? heehee
