…And pride definitely wenteth before the fall today. It turns out, when I read the crochet pattern properly, that I had gone very wrong indeed. My ‘popcorn’ bobbles were all wrong, and I hadn’t read the last round properly either, so instead of being six-sided, as the picture in the book clearly illustrated, my block was twelve-sided.
But I can pull out the blue block and recrochet it, and I have done a new block (reading the pattern and following it properly this time), and have produced something that does actually look like the illustration! That’s positive!
