Fabric A: Lay your hat form on the wrong side of the fabric. Using the ruler and fabric marker, mark the fabric 3⁄4″ from the hat form edge, entirely around the fabric form. Cut it out. This piece should be 3⁄4″ larger than the form on all edges. Then cut one 4″×12″ strip.
Fabric B: Cut two 4″×12″ strips and one 2 1⁄2″×17″ strip.
Buckram: Cut three 1″×12″ strips and one 5/8″×17″ strip.
Felt: Trace the hat form shape onto your felt. Cut just inside your tracing. The felt should be 1/8″ smaller than the form on all sides.
Pin fabric A, with the right side facing up, to the outside center of the hat form. Then, with a needle and thread, do a running stitch 1⁄4″ from the edge of the fabric, around the entire piece. Gently pull the thread so that the fabric tautly wraps around to the underside of the form.
Once you’ve stitched around the entire piece, tie a knot. Then go around the form again, whipstitching the fabric’s raw edges to the underside of the form, being careful not to stitch through the top outside layer of fabric.
