Yesterday I quilted the quilt with the black polka dot sashing and had no problems at all. I did straight line quilitng a quarter inch from the seams. That leads me to believe that my FM problems are one or more of the following:
a) poorly wound bobbin
b) poor quality thread
c) poor quilting technique.
I am betting on c. I think I may have been moving the fabric too fast for the speed of the machine. Oh for a stitch regulator!
Meanwhile I have started another wonky log cabin. My scrap pile seems to be growing again. Or is it merely a ploy to avoid the dreaded FM that needs to be done on the farm animals? I plan to do a bit of quilting on it every day before I allow myself to make any log cabin blocks. Am I strict enought to do that? Time will tell.
