It is a personal thing if you choose to continue or not. Some people can forge ahead and others have to set it aside. Some projects take longer than others do, It is a hame that a comment can make it hard for someone to have joy in what we do.
I found myself working on a lap quilt for my dad once and while putting together the one block, totally hated it at the time. But I knew that I picked the fabric for a reason and the fact that I have a really hard time pulling out perfectly good sewing, made me continue anyway. The piece sits out on the back on my dad's chair most of the time, hardly ever used as he doesn't want it wrecked, he shows anyone that comes to the house and has gathered it's fair share of compliments.
Some times you have to go with your gut no matter what others think. The quilt as a whole looks so much different that when it is in pieces.
There would also be a whole lot few quilts around if we all stopped what we were doing when someone didn't like what they saw.
