For knitting covers for those wire hangers that you get from the dry
cleaner, what I do is this: On size 5 needles with 2 strands of 4
ply yarn, or if using 2 ply you could hold 4 strands at a
time, cast on 5 stitches, and knit for 100 rows, and cast off.
Leave a long enough tail to sew the cover on the hanger. This is a great way of using up small bits of yarn. When one strand runs out, put another color strand in. Starting from the bottom of the hook begin to wrap the cover around the hanger, holding onto it with your left hand and start sewing. It's easy, just kind of hard to explain.
I just was thinking about 12 years ago when my friend Emily gave me
a bunch of crochet thread, just a bunch of tiny left over balls of the
crochet thread from her mom's stash. I thought making coat hanger covers
would be perfect of which I must have had enough for about 5 or 6 of them.
I used about 6 strands to knit these covers to make them thick enough.
There were all different colors, and since I'm totally blind, my neighbor
would pick out about 10 or 11 of those little balls for me, as I was beginning
a new cover, of colors that would go together. As I said before
in my instructions, as soon as I would run out of one strand I would
add in another strand. I used to be able to see colors. I would have loved
to see this mixture of colors mixed in.
