Update...took to dealer this morning...I hr, one way! Besides the funky stitch, I had decided maybe it was linty, so cleaned the bobbin area, but when I put it back together...it ate the fabric...so I just unplugged, grabbed my purse and off I went! Dealer/owner was kind...she told me the "trick" of removing/cleaning/replacing bobbin the correct way....that should be in manual, but not! Then I showed her the funky blanket stitch....answer was....must be fusible used, or needle to be replaced, even though new, try another. I didn't even mention that my old Viking "took over" without new needle and no funky stitches........so see why BL is not my wisest investment.........will be " shopping" soon........
