I think it takes practice. One of the reasons is because none of us have complete projects laying around all the time ready to FMQ. So we practice on little squares then we grab a big quilt, wall hanging or whatever and it moves differently. So it is a harder skill to acquire.
I spend a lot of time piecing my quilts longer than I do FMQ and I haven’t mastered that skill 100% yet either.
How many here have stopped FMQ and moved to Longarm quilting (not the computerized program type) were you more successful?
