I am attempting to knit my first pair of slippers
. I found a cute pattern here called Cozy Whisper/Cotton Chenille Slippers. http://www.straw.com/cpy/patterns/cotton_chen_whisper_slipprs.html
The first step is to CO 24 sts and work in a rib for 3". I did that. Then I BO 6 sts, worked 12 sts in rib, BO remaining 6 sts. What I am left with is confusing to me. I have 12 stitches on a needle, having cut the thread after the final BO of the side 6 sts.
I am supposed to work the 12 sts on the needle for 5-7" (foot bottom) now. How do I work in a new piece of yarn?
Thank you for any suggestions you have to share
