This pattern is for a very simple dog sweater. A short ribbed collar, and the body in stockinette. It starts on DPNs (though you could use magic loop) and is transferred onto a 16” circular needle.
Size small, fits around 12-15” around the chest. Medium, 15-19” and large 17-22”.
If you know how to knit, purl, and M1, you can make this!
4.5 mm 16” circular needles, (again, you could use magic loop)
4.5 mm DPNs
3 mm crochet hook
Spare yarn or stitch holder
5 stitch markers
I used a different colour yarn for collar.
There are some pictures, and a few video links.
