Butting in here, but I DO know that answer. WIP is work in process. I am fairly new also to this board, so am also learning the acronym for some phrases.
As far as how long does it take to complete a quilt. There is no perfect answer. We all have varying factors that affect how much time we can spend on a quilt. The skill levels and details of a quilt can vary so many ways, it is impossible to have a "correct" time to complete a quilt. Just the fact that you are dealing with such medical problems and are still quilting is so inspiring to all of us. Just work at your own pace, enjoy the process, and don't put the time stress on your schedule. This craft is supposed to relieve your stress and give you peace. If you do need help with something, these quilters on this blog are awesome. I have learned so much just reading their responses. Enjoy your quilting!
