Are you doing those by hand?sorry, I've been away. Getting to that promised review. I appreciate the gift.
Ayup, by hand. No problem; sounds like you've had stuff going on.
How are you doing the filler?
It's all by hand. If you mean the actual pattern, it's three vertical hashes, 3 horizontal, 3 vertical, and 3 horizontal per square, going clockwise from top left. Doesn't really matter; Whatever works for you.
