Well, let's see.
Wash, dry fabric
iron-well it will sit in the basket for a week or two before I get around to ironing,
then I start cutting, oh-look at that color wouldn't that go good with this other project I'm working one. a couple days before I get back to finishing cutting.
Piecing-going good-until I have a pile of crumbs that I start sewing together, so a couple days later get back to piecing my top.
Then get bored with the pattern and start something else, oh, I really should work on that..
So for me it can take about 4 months to actually finish a twin size top. I get distracted easily-but hey when I'm in a finishing mood I can finish 5-8 in a week.
Oh, to actually quilt it, add another month I get discouraged quickly. Or I send it out to a long armer.
