Help. I'm having a problem getting my stitch length long enough to try to quilt. I purchased the correct walking foot from the sewing shop. I removed the thread cutter before I attached the walking foot. When I try to stitch on my sample, my quilt sandwich will hardly feed through and I'm getting a teeny tiny stitch - maybe 20 stitches per inch or so. I've cleaned and oiled my machine, put in a new needle, rethreaded, and put in a new bobbin, and fiddled with the tension. I don't know what else to do. There must be some sort or adjustment I need to make, right? I'm giving it up for tonight and will start fresh tomorrow. Any suggestions will be most appreciated. Thanks.
