All my quilts are fairly simple and usually I can finish piecing a top in less than 2 weeks, so I usually finish one before starting the next. But I am retired now so can devote as much time to it as I want. I admire those that take on complicated projects that take months or years to finish, but I just don't have that kind of patience! Ocassionally I may stop my current project if I need to make a quilt for a gift with a deadline, but then go right back to complete the top I was working on. I have picked out a pattern and fabrics for my next 6-8 quilts, so always have one ready to start as soon as one is done.
