I agree about the bind offs (hadn't thought of that yet!). But, the original pattern is 20 rows. If I'm continuing, row 28, for example, will be the same as row 8 was. The bind offs are on row 8, row 14, and row 20 of the original pattern. So I'm thinking maybe row 28, row 34, and row 40, row 48, 54, 60? And row 20 (which was supposed to be the last row of the wedge), I'd have to do like rows 8 and 14, except for when I actually DO get to whatever row is the last row of the wedge. I haven't figured out yet if the wedge will have to be 60 rows total, since I'm multiplying everything by 3. The original pattern's even row right before the last row of the wedge (row 18) has 9 stitches that don't get worked on the left needle. So, with 45 stitches, should I knit until the comparable row has 27 stitches that don't get worked before I turn the knitting and do the last two rows of the wedge?
I'm not a math person, so I'm confusing myself, but I am determined to get this right! The only actual pattern I've found for a round short row blanket says I need to knit a swatch to figure out how many stitches I need to make up 18", and I do not want to have to do that. Because, as I said, I'm just NOT a math person!
