Westalee's 3-1/2" Daisy Template Ruler allows you to create individual flowers and circular floral patterns when using a rotation pin for centering. It's recommended that you use Stable Tape (not included) on the back of this template to prevent slippage. The Daisy Template requires a 1/2" ruler foot (not included). Please note that these acrylic templates are specific to the type of shank your machine uses: low shank, high shank, or longarm. Don't hesitate to get in touch with us at (888) 824-1192 if you aren't sure what shank your machine uses, or check out this handy Ruler Foot & Template Size Guide here.
