It's a fascinating technique, I've always wanted to be a drawer, but I'm not good at it, so I got a way to draw, which I do by knitting.
Definitely, with this technique you must have a lot of concentration, a mistake in a stitch, possibly distort the drawing you wanted to do. It also involves special attention in the handling of the yarns.
Good to have this technique in your wish list, I recommend you to start with small projects so you can get familiar with it.
I send you a big hug full of blessings💖.
