Thanks for the reply! Unfortunately, I'm still stuck because when the pattern says: "K 17[19, 23, 27], Cable Patt 9," I undersand that to mean knit for 17 stitches, then follow the cable pattern for 9 stitches, and I can't figure out how I could do this cable pattern for 9 stitches.
The only other way I could interpret this is that I knit 17 stitches, then follow the Row 9 instructions for the Cable Pattern - is that what you meant?
Then, after completing the cable part, I would join a second ball of yarn and knit the remaining stitches in that row?
Maybe I'm making this more complicated in my mind than it really is, but I'm totally confused, so please bear with me!
