which decorative stitches have you been able to use successfully with the accu-feed system? I know the regular zig zag can be used. Supposedly any stitch that doesn't go backward should work but how do you tell? Do it with regular feet first on some scrap? Does anyone have any stitch numbers they've used with the A/F? I'd like to keep a list on my machine. Since I only do straight line quilting maybe some deco stitches will liven it up a bit.
