A bit of progress- I’ve now sewn my 15 selected blocks together. I might put the discarded log cabin and courthouse steps on the back, but maybe not - really don’t like my versions. The last row has one slightly too big block , paired with one slightly too small one on the opposite side, making the join with the previous row slightly off, but hopefully no one wandering into the spare room will notice! I’ve got a 4” border to put on, then on to the sandwiching.
