Machine skipping stitches
I am seeking help from the pros on the Board and those who have solved this problem themselves. When using a simple straight stitch on a quilt sandwich, no problems smooth and even stitches without tension problems. When I reset for free motion quilting (dogs down, new needle, re-threaded the machine, changed the bobbin) it get skips in the stitching. It doesn't have a pattern to the skips. The skips are not on curves or in any predictable number of stitches.
Any ideas of what the problem could be? I have a quilt with a deadline and would like to get it finished.
Thank everyone.
