like many I have the bernina 440 stitch regulator. When I first. Had the machine I played with my new toy. 2 years down the line I just go for it. Sometimes straight lines with walking foot,others , normal open toed spring foot. I use feed dogs up and down . To. Be honest I just go on a practise piece then on the main quilt and please myself. Honestly no difference. Over time small stitches have got bigger and big stitches smaller. Some days they are perfect especially as I did before Xmas 12 tops quilted in a row, perfect by the end.
those of us working from home on DS machines have long spells without quilting while we make the blocks. This break makes us forget. My dogs and cats have my sample pieces and love them. Old ones get stuffed in a big bed they have. Periodically I was hand empty out. The animals love polyester in centre but I find that not my idea of middle especially on a domestic machine as it catches too often.
