Worked a bit too much, on the rather enjoyable Open Register of Interests aka. "declared." project. Got better at postgres.
Learnt alternating rows of Y stitch and shell stitch to make a nice crochet pattern.
Two days later realised the thing was coming up way too small, so I'm going to have to abandon it and start again. I'm using the wrong yarn - but it's a bit mysterious because if anything it should have come up too big. I guess doing it with crochet thread would make it looser and therefore bigger? Not sure how to salvage. I might apply the same stitch to a more simple pattern.
