cartridge belt stitch on Waterfall Vest
Just started Prism's Waterfall Vest using the cartridge belt stitch pattern. The pattern itself is simple, but the instructions given say to increase one stitch on each end every other row and work them into the pattern as you go.
These increases are really throwing me for a loop. Has anyone knit this pattern? Recommendation for using kfb or m1 for the increases? Ordinarily I'd make the increase in the secod stitch but at the end of the row one the last two stitches are sl1 k1 and I don't think I should increase in the sl1.
Also, any suggestions on how to "work the stitches into the pattern"?
