But midway through the booties from the set I ran out of yarn, and I couldn't find any more from the original dye lot (which was mission falls superwash merino).
I'd wanted to add in some thin stripes and what Joelle Hoverson calls "blips" of bright turquoises and jade green from some alchemy yarn that I'd been saving for a special project. I think I will try to do this another time, so I'll note it here. The trick is to knit in a 2-row stripe on the wrong side, so that the stripes are skinnier and blippier on the right side.
^ Pickles boot unseamed and loosely pinned into bootie shape, before I pulled it apart.
Then I did the soles with the Alchemy Temple. Temple, which is superwash merino, smooth and doesn't pill, is easily my favourite yarn for kids.
