I participated in my first two last year. Swapped table runners. Despite making a runner in the person's favorite colors and motif, I never heard from her or even received an acknowledgment of her receiving the runner. Left me with sour taste in my mouth and disinclined to participate again.
The other one I did was a pincushion swap, which was much more enjoyable. Got a nice pincushion, and the receiver liked the unique one I made for her. So, mixed experiences.
I realize we all have different tastes, levels of skill, and busy lives, but I thought it rude to not even acknowledge receiving. Hope your experience is a positive one!
