Another pattern where I was sure that I’d done a zig-zag version! I’ve searched through pictures and my big bag of socks, and find no evidence that I did anything more than plan them. Here you can see what the inside of a mosaic sock looks like (Opal sock yarn, again). The floats are, at the largest, 3 stiches, so not particularly long. Because with mosaic knitting you are only knit with one color at a time, you can see bands where the floats are minimal, and also that the floats come in bands of rainbow then black, then rainbow and so on.
Something I noticed around this time was that the colors stand out more than the patterns, such that a group of these socks made from the same yarn all look very similar, even if the actual mosaic pattern is very different. This helped me decide that it was okay to only do one pair of socks per pattern.
