I opted to make a single color, which really didn’t take any adjustments to the pattern. Caron Simply Soft is apparently not as stretchy as Red Heart Soft, though, plus I have what looks like a more recent model of Swiffer Sweeper with a slightly larger head than the old one, so I had to add rows. I did one version with eight rows, and it still stretches out too much, leaves too much Sweeper showing through the sock. 9 rows has almost got it; it certainly makes a useable version. I think I’m going to try another at some point with 10 rows, but also add some more decreasing at the end to keep it fitting nicely. Need to take a break and work on something else for a bit, though.
