I just finished quilting 16 quilts about 40 something by 60 or so inches. I sandwiched 2 or 3 a day. Now I am machine sewing on bindings. These are for foster kids in my county to be given at Christmas party. These are about 40 or so for this year. After these are done I plan to make more. I love all parts of quilt making and work on them 5-6 hours a day.
To get yourself moving on just one quilt, tell yourself at least you don't have 15 more to go.
