So, this was unfair
I tried rosegrounds and spiders again, but with different thread. It looked okay. I'd tangled up at some points, so I knew it wouldn't be perfect, but when I took it off the pins....
Hallo? Excuse me??
Extremely rude.

Attempt that resulted in a thing I took off the pins number 2!
I'm pleased I managed a few more spiders/rosegrounds this time.
The edges fought me, I think I overthunk it, and I think I needed to tighten that final spider a little.
I think next I'll go back to patterns 3 and 4 and work those a little more.
