I have a BL...not that high end one, but a midrange. Watched and then tried MSQC tute using the orange peel, four patch thingy. Worked okay until I tried sewing the blocks together...as it approached the thick edge ( backgrnd, peel seam) it would not stitch...now this bulk is not across the whole foot, just on the left side so the foot had to sort of lean over it. Skipped stitches no matter what I did. Took it to dealer with a few blocks...did the same for dealer...claimed never saw that before...left machine so "tech" could have a look.. Two days later...picked up machine tech said worked for him....came home tried one...same thing.....give up on this machine....finished project on my old Viking which stitched those humps without a hiccup! Time to dump BL and look into viking
