Frogs are an ancient decorative closure that traveled from China to western Europe in the late 18th century. These fasteners are created by shaping a variety of materials into knotted patterns, such as the classic four-loop and the double swirl shape. A frog closure can be subtle when matched to the garment, or bold when made in a contrasting material.

This closure is often functional, with a working, knotted button from matching fabric. But don’t overlook the interest created by adding a button of contrasting material, such as wood, metal, or clay.

Multiple frogs can provide the focal point down a garment’s front. Alternatively, a single loop and button can often be an understated detail. Creating a handmade trim and closure adds a level of quality not seen in ready-to-wear clothing. Though frogs look complex, they can be made easily by following these instructions. Once you feel comfortable with the version shown, you can experiment with your own styles.

Materials and a Knotting Guide

This project can be as easy or involved as you like, but to start, the items you need are knotting material and a template.

Tubes and trims

Traditional options for creating a handmade frog closure include rattail cording, soutache, decorative braid, jute cording, narrow lace trims, packaged or homemade bias strips, and corded tubing. Experiment with other ribbons and materials to find new and interesting results. Keep in mind the scale and proportion of your selection in comparison to the fabric and garment design. A dainty silk blouse needs a fine, lightweight closure, not a chunky one. The narrower and more supple the trim, the more detailed the design can be; a thick, heavy cording creates a heavy finish.

Making your own corded tubing ensures an exact match to the fashion fabric. To make…
