Hi Joyce, I used to live in Midland many years ago while my husband installed a computer at Dow Chemical. I use cotton yarn and knit two styles after trying many patterns that stretched out and got misshapen. My favorite is started at one corner with 3 stitches. Next row knit 2sts, yarn over, knit last st. Next row, knit 2 sts, yo and continue on this way till you have 60 sts on your needle, then start decreasing this way. Knit 1 st, knit 2 tog, yo, knit 2 tog. Keep doing this till you have 5 sts left. Then knit 1, slip 1, knit 2 tog, pass the slipped st over the stitch you just knit tog, knit last st. Now you have 3 sts. Knit them once, then knit all 3 together and you're done. It takes me about 4 hours to knit one.
