This year, I only completed two of my own (wall hanging and large lap-sized).
But (1) I work full time with a 1-hour commute each way, (2)have a small farm (30 acres -5 horses), (3) we had a large veggie garden this year so did a lot of canning and (4) I did a lot of deer hunting this fall.
However, last year, because of the UFO Challenge, I finished 12 - averaged 1 per month - so I was very happy with that.
In addition, I do longarm quilting for a handful of regular customers, and often those are custom quilting, so that takes a lot of my time in the evenings. I'm hoping to get back to 12 a year in 2018. That's a number that gives me a feeling of accomplishment without feeling pressured or stressed about it.
So, it varies from year to year.
