Have you ever done a round puzzle?
This was my first and quite a different sort of challenge. Several very tiny pieces, other pieces in very strange shapes and the green most of which I did last was difficult. I persevered and met the challenge.
Puzzling will continue until weather warms enough to get out and garden. Oh, wait. May be difficult to do one handed. My surgery to fix right thumb and carpal tunnel is the 31st. I'll wait and see.
