That is a LOT of stitches, so it's understandable that it will be slow going. Even so, ten rows it great progress, 4640 stitches...

I've seen some really cool stitch markers, but I only have one set of boring yellow plastic ones. I should get some fun ones because I started a sweater last year and just could not get the pattern to go right. Never had that problem in over 40 years of knitting, so I don't know if it's me or the pattern, but I think stitch markers might help.
