I’m usually in my quilt room 4-6 hours a day. I have a sit down mid arm so am not dependent of someone else finishing my quilts. So start to finish is really fast. I can do a baby quilt in 3-4 days and a lap quilt in a week or so. I tend to get bored quickly so I usually have several projects going at once. Right now, I have 5 tops done, working on backing for last one now. Planning a marathon basting session, followed by some marathon FMQ’ing. Goal is to have 3 of them done in 2 weeks. My stack has to get smaller. Then its time for a massive reorganization and cleaning of my room. There is no one “right” speed for a project. Do what makes you happy!
