Then, the grip holds the quilting tool in place, eliminating slipping while you quilt. · Black and White dashed guide lines are visible on all fabric colors · Easy to use. Simply install a ruler foot on your machine and quilt along your chosen edge of the template for endless design possibilities. · Palm sized tool allows for maximum control, preventing broken needles and crooked lines. · Use Shelly to quilt clamshell designs from either side of the tool. Also great for orange peels, flower motifs, arcs, and leaves. · Create all-over designs as well as block designs and borders. · Needle stops ensure perfect starting and stopping points when stitching out designs.
