Follow along as we look wrap up the course with a look at using a prong buckle for the strap as well as adding an elastic strap to the heel.
For this example we are using the double strap variation on the 18-inch doll shoe pattern. The buckles are just under 6mm wide on the interior which fits a1/4" strap.
You can find these buckles at Pixie Faire:
The elastic used for the heel strap is clear 1/4" wide elastic, usually designed for swimsuits or lingerie garments.
