I am not paper piecing.
Originally 77 quilters enrolled to do the sampler; some participants, I think, chose to not have their names on that list. Some have quietly dropped out; some have gotten behind when life/jobs got in the way; a few who quit did post their intention to do so. It's difficult to say how many of us are still doing this sampler because it has always been a "work at your own pace" project.
Note to JanRN: Your blocks are just fine. Some of your color choices are absolutely great. I especially love that swirly grey/black fabric. You should quit beating yourself up!
