i have done a couple whole cloth quilts, but i machine quilted them, it was great fun to (practice) on a blank canvas! they turned out fabulous and everyone wanted the queen size one...it landed on my bed!:)
the other one was small and i encorporated it into a larger pieced quilt later. so i guess that one doesn't count.
then queen size one took me about a week to machine quilt (maybe 5-30 hours i guess)
i am looking forward to starting another one, have been envisioning it for a while but have a lot of 'catching-up' to do before i can start something like that again.
