I think that the first garter turned out very similar to the etching. It is being modeled on one of my Christmas presents. I used 100% cotton crochet thread. It is stretchy enough to fit on my upper leg or lower leg which is great depending on what kind of reenacting socks you wear.
The garter is a lot bigger than how I pictured it when looking at the etching. But they fit perfectly. I was very worried at trying to loop the knitting because I had never tried to pick up stitches from a cast on but it worked out perfectly with very little issues.
Hope you enjoy!
