I'm all for traveling, though it may at times be difficult. Besides being entertaining, I learn things. Heck, I even learn things from other people's trips. One of the members of my knitting group went to Germany last month. When she returned, she brought back instructions for a short-row heel. She raved about the heel, and even had a sock her German friend had knitted using the instructions. The joins were very smooth, even smoother than a wrap-and-turn short-row heel or a yarn-over heel (the one designed by Priscilla Gibson-Roberts).
The heel uses a "doublestitch" instead of the yarn over or wrap and turn. It is called a Boomerang heel. Of course, the instructions are in German. That's no problem for her (German is her first language), but presents a huge problem for me. I've looked around the internet, but can not find instructions for a boomerang heel. I did find something close, though.
The instructions I found do call the stitch that joins the short rows a doublestitch, but the heel is called a Yo Yo heel. They can be found here at Tess Knits. I don't know the differences between this and the boomerang heel. I will have to wait until I can either watch the boomerang heel being knitted or until I get translated instructions to see if there are any differences. The knitter who brought back the German instructions wasn't ready to knit socks just yet, though she will get to it soon enough, I'm sure.
Edit: I think I've figured out the yo yo and the boomerang heel and explain my theory in this post.
