The other cool thing about this picture is that you can really see how a granny square, at least one of mine, comes together. I chained 4 and slip-stitched them together, then I chained three to make my first stitch of the round. That stitch tends to look just a little different than the other stitches. If you’re ever trying to figure out how something was crocheted, learning to identify that starting stitch can be really helpful. Here, in the red circle, you can see how that starting chain-3 stitch looks more like a braid than a twist. You can also sometimes tell up at the top, where the blue circle is, because it doesn’t seem to quite come together. But, depending on the yarn, this isn’t always true. The furrier yarn just southwest of the square we’re looking at hides its starting point almost completely.
All the squares are connected and the border is completed. All that’s left is to tuck all the ends on the connective tissue. I don’t know how long this might take. But I will say that it looks good. I have never made an afghan that appeared to be so simple but was such a pain in the ass. And I probably won’t again (though it is a good way to use up ends, so maybe it wouldn’t be so terrible to do it over a few years?). But it’s going to be really cool. I’m really proud of it.
