If by Mondays you mean mercerized cotton. This stuff is the suck to work with. It's so slippery that I have to tug every single stitch, which is impossible to do evenly every time. If I were in the round, that would be manageable, but since knits and purls slant differently, my stockinette stitch looks like crap. I have made some progress, past the underarms and nothing but st st for a good 10" more.
