Being one of the Moderators of Quilting Bee Blocks, I've seen this topic come up a time or two. Bee members dropping out unexpectedly, some even having the audicity to skip out after their month was over, etc. The absolute worst that I've encountered was when the Adminstrator herself left the entire group hanging without even a peep. Yet, don't let any of this frighten you from joining a bee or swap...because these people are the minority and as you'll see the quilting community is "fighting" back.
Let's be honest, there are a handful of legitimate reasons why you might have to leave a bee or swap, and while there is sadness, most times there are no hard feelings if you contact the adminstrator of the bee/group to let them know ahead of time. Other arrangements are usually made by Angels or replacement members can be found and things go back to normal.
I recently saw a post from Cherie at Sew and So Quilts, who linked to Tiffany at Lower Columbia Modern Quilt Guild is the creator of the Swapping Integrity Pledge.
I'm taking the pledge, how about you?
