I’m going to try an interesting technique to finish the bottom of the V-neck, which is made somewhat easier because I’m working top-down (I wouldn’t like to try this little experiment if I were working bottom-up, though it would work out fine if one could be quite sure of one’s row/round gauge).
I want the two mirror-image edgings to meet and miter themselves away, coming to a sharp point some way down the body of the sweater. That means I need to keep doing an increase at the outer edges of the two sides of the edging, but since I need to keep the same stitch count the whole time, I’ll have to do a double decrease on the center three stitches. Oy, that sounds confusing, but I don’t know how else to say it. And I’m not sure I can chart it and have it make sense either.
So I’ll continue to do an increase every 4 rounds between the stockinette body and the neck edging, the same schedule and locations as the increases I did to draw the two sides of the V-neck together, and on those same rounds, I’ll do an appropriate knit or purl double decrease, based on whether the new resulting center st needs to be a knit or purl. I did go ahead and attempt to chart it, but I left the center st as just knit the whole way. I’ll work the double dec as a knit or purl version of the centered double dec (sl 2 tog, K1, pass 2 sl sts over) based on what will look best in the fabric at that moment. Whether the chart is comprehensible to anybody but me is a whole different question!
And actually, I’m glad I did chart it, as the edging stitch pattern will end far much farther down than I thought it would. But I’m pretty set on having the bottom of the V-neck come to a point, to let the Mistake-Stitch Rib go as far as absolutely possible. We’ll just have to see how it looks in fabric. And no, I probably won’t frog it no matter what it looks like. That’s part of the adventure!
