My friend, Judy Laquidera, has at least a half dozen people MAKE different sections of her quilts following her patterns. She has people with little experience and people with a lot of experience. I think it makes a big difference.
At least most of the errors aren't as bad as the one I read about last week where a whole printing of a cookbook had to be recalled and trashed.
If you don't know what I'm talking about just Google - Australian Cookbook recall. Should be the first hit. Kind of puts it all in perspective.
