The trick I use the sew vinyl is tissue paper. I would put the tissue paper on top of the vinyl before sewing, then sew all the stitches. Using tissue paper would allow the vinyl to pass through the feed dogs more thoroughly. After you are done sewing, you can rip the paper right off. Use tweezers to get the small bits out. Also, if you're worried about your needle dulling, use a thicker/bigger needle.Hope this helps!
