For participiants with advanced skills in shortrow-knitting as well as in Moebius-knitting, I held a workshop to learn how to construct a Moebius in desired length and width and also Swing-knitting technique.

My example was designed for several ways to wear (as shown in pictures) and I also designed the mistakes you may make designing your own.

Above this the knitters were shown an easy way for a Moebius-cast-on where you can easily count your stitches.
I didn’t see this technique described yet.
Here is a download in German.
