This case takes about ½ skein of worsted weight 100% wool yarn. Cascade 220 is what I have here. It is nice to work with and felts evenly. Mine took 2 washings in a zippered pillowcase with a pair or 2 of jeans for agitation. Use hot water. I have a toploader so I couldn’t check the process, but it took 2 to 4 cycles depending on the yarn.
For the cellphone case, I used the double pointed needles. Mine are size 9. Cast on about 12 single strand stitches and knit every row for 5 rows. Pick up stitches on sides and original cast on row. Divide evenly over the rest of your needles. I guess it would be 3 on each side and 12 plus the 12 you had, so 30 stitches?. Knit until 33% taller than your cellphone. Cast off. Pick up stitch near the center. Make 3 stitch I-cord loops. One about 5” long and the other about 10-12 inches long.
This is before felting. Probably the size big enough to hold a cigarette pack. . .
After felting, Turn off cellphone, wrap thoroughly with plastic. Shape case to your phone. It’s a bit like working with clay! Carefully remove phone and hang to dry. This takes about a day.
I have also done 10 stitches with 2 strands of yarn treated as one.
