On several groups I have done swaps, not having a local network of quilters at the time, I thought it would be fun to try. It seemed like more and more I never got stuff in the colors I asked for, blocks were undersized, but I didn't want to be b****y, but my husband mentioned that I seemed to put a lot of effort into this and didn't seem to get much back.
I guess the final straw was when I did a Secret Santa. I made several small gifts to keep the cost down, shared some quilt shop FQ from my stash, a couple of patterns I got on eBay and some very nice chocolates. My partner had to be asked if she got it and all she did was say yes, I got it, thanks and I got her stuff she had specified. Worse was what I got back, a very flimsy FQ in colors I put on my dislike list, a few loose hershey kisses, a cookie cutter and a pair of footies that smelled like Snuggle fabric softener. I already had the same footies and knew they were sold in a three pack.
So no, I haven't totally sworn them off, but I only do about one or two a year and only on established swaps.
