This is a pattern for 3 different buttons: Medallion, Heptagonal Circles and Bullion Spiral
A small doily-like circle is crocheted and used to cover a button mold (found with sewing notions).
Rather than use the shank to sew the button, the shank is removed from the button mold and replaced with a pin back.

Materials needed:

• Thin rolled or stamped brass rings.
• PETE Ring. Pattern says available at plumbing supply shops for faucet gaskets. If a PETE ring can’t be found, pattern gives instructions for making one from plastic.
• Button molds varying depending on selected button pattern.
• Glue gun
• Pin back

This requires a size 12 thread hook.

Basic stitches: Ch, sl st, sc.
Special Stitch: Bullion
