How to Make Hairpin Lace
When I was a kid in Kansas, I learned how to crochet hairpin lace from my grandma. Though my mother discouraged such pursuits, the kindly next door neighbor man, who was a welder by trade, made me a hairpin lace loom from a welding rod, which was sturdier than the store-bought one I had. (Terminology--this is also called a hairpin lace fork--same thing.)
Through the years, I've experimented with the potential of this crochet technique, so I thought I'd show you some of my research. I'm not going to burn through space with a tutorial on crocheting the hairpin lace, because there are some good videos on the internet showing this. One is here, another here, and yet another here.
Once I discovered the potential of making a nice trim from the hairpin lace, I had a machine shop make me large looms--I have several, 30" long, and different widths, from 6" all the way to 10". This way I can work very wide ribbon.
Here's my very first hairpin lace loom from all those years ago. The width, measuring outside to outside is 3 3/4" wide, and it's 15 inches long. I've worked a length of the crochet on it, using 7/8" wide grosgrain ribbon.
Now the fun begins!
You can do different things to this row of trim. The first idea, is to chain the loops together, like you would when casting off during knitting. Use the crochet hook to pull the next loop through the previous loop.
