It depends on my time and motivation and difficulty of the piecing. If by finish, you mean start to end, probably no more than two or three. I am notorious for making several tops before I finish one completely, so that can spread over more than a year. The exception is the year I make at-shirt quilt for a grandchild. That gets started the first of the year they are in 8th grade and finished for Christmas. I have to work the quilting in with my yard work, volunteering, exercising, hiking, and grandchildren. There just are not enough hours for all I want to do.
