thanks for the clarification.
The pattern is just knit all rows, until you feel like it is long enough, for a dog or a cat.
Then after you finish it, repeat it so that you have a second one, same size or a few stitches larger if you want to stuff it.
Sew it together, put the stuffing in If you want to.
And then it's done!
The needles i've been using are size 11 straight needles. They work pretty well. If you want, you can prob. go larger.
