Ooooooh a comment. I knew I put that link there for a reason. Just have to post a response.
Yes, that knitting machine looks scary, but bear in mind, I'm working intarsia with a bunch of colors. Eighteen color changes per row if you are counting. If you were hand knitting it would look scary about now as well. Unless you were the kind of wierdo that weaves in ends as you go along. Actually, the mess that is pictured is quite under control.
To learn, I started with one color, then moved to basic 2x2 cables, then tried stripes. After that I did an intarsia heart on a sweater front. Then I tried the chicken sweater from a book called "animal knits". It got scary. It became a mess. I left it on the machine for three month's hoping it would go away. It didn't. I finally ripped it off the machine and threw it into the trash. So, there's the answer to what happens when things turn into a tangled mess. Avoid, then destroy. This may be a deviant aspect of my personality.
This is the first time "back in the saddle" since the terrifying chicken incident.
My knit guild has an impossibly huge supply of craft yarn that is being used for charity projects. We just drop by one of the storage locations, pick what we want and bring back what we make. I took a good sized shopping bag home when we sorted it over a year ago. I am taking advantage of this to develop my skills and confidence with the scary machine cost free. Because of the abundance of the yarn, I don't feel the need to conserve, so tossing a mess away rather than picking it apart and re-using the yarn is an option I can live with. And sometimes, I even end up with something to donate. When I began I made several toddler child sweaters that were donated.
So, everyone in the United States, have a wonderful Thanksgiving holiday.
