sort of cynical...but do many of the guild members send their quilts out to you and pay for your skills?
I ask this because one of the reasons I don't belong to the nearby guild is they want everything for free. The want to local shops to provide fabrics and batts for their money makers, but when they buy for themselves they go down to fabric depot in Portland or order online.
One year they got their free raffle quilt quilting and had to take every bit of it out. Then they washed it to remove all the holes and the fabric dye ran.
If someone doesn't support your work you owe them nothing.
But I admire you for carrying on and you probably learned a lot of lessons that will help with other big quilts.
