I think the one yarn I used is what is causing the rippling. The purple is a cheap polyester yarn I got a bargain on and I think it's the rippler.
I've been doing a little on my scrap 'ghan. It will be a while before it's finished. It is a nice brainless project.
p.s. I did a count on the tomato sauce I canned: 8 qts, 12 pts, and 20-- 1/2 pts.
