Pattern for Rick Rack Edging and Lace Insertion
Lately, garments embellished with rick rack are showing up on store racks, so these crocheted rick rack edgings should fit right in. A few ideas for uses would be as a trim for the cuffs of jeans, added to the pocket flap of a girl's backpack, sewn to a hat or added to the hems of garments.

This illustrates the parts of the rick rack referred to in the patterns as the base of the scallop and the top of the scallop. |
The following photos make it easier to understand where the stitches are to be worked in the rick rack.

This shows 4 dc worked in the top of a scallop and the hook inserted in the base of a scallop, ready to work a dc there. You can see by the two double crochet stitches worked in the base of the scallop before that, the areas in the scallop base where those two dc's should be worked. |

Here's a look at where the second double crochet worked in a base of a scallop is done. |
These instructions and images copyright © 2000 Sandi Marshall. The patterns on this page are based on a double-tier rick rack pattern printed in 1916 in the book Novelty Crochet Patterns but I changed the design around and also varied the number of stitches used in order to update it to be used with size 10 thread. I also rewrote the way the instructions are explained to make it easier. The 1916 pattern book had only one black and white photo of their edging. All photos on this page and on page 1 of this article are my own.
