These were actually 12mm plastic circs I got on clearance when Jo-Ann dumped their plastic needles. So, don’t know about the mm being off.
This yarn is discontinued, and I bought it on a clearance. It is mostly pink, but has mottled coloring with other soft pastels in it.

If you look closely, you’ll see I’m wearing hair curlers! This was made very quickly as I got real tired of my neck freezing when I had curlers in.

Nothing fancy, just used reallly big needles and cast on 10, and kept knitting till it was the size I needed it to be.
