Anyway, I made a continuous "Granny" square to 20" and decided to turn it into a cushion cover, so made a back to go with it. After crocheting a border to join 3 sides, I was waiting for the cushion inner to arrive, which it did this morning. I've now closed up the final side, and even if I do say so myself, am rather pleased with the result. I'll probably regret closing it in rather than putting a zipper in it as knowing me, I'll probably spill something on it. However, I'll cross that bridge at a later date.
