I cast on about 15 stitches and began increases with yarn overs. which I knit through the back loop on the return row. It hides the y/o better that way.
I added the green yarn and did a row of y/o, k2tog, for easy lace, keeping the firs three stitches and the last three in garter/Maybe you can see the yarn overs here, which is on the back side. I did three on each side, and then knit the next row, then four, knit the next row, five, knit the next row. It seems to be working. The real difference is that the rows do NOT curve like they would if knitted top down. I maybe don't care/
