Excellent idea - and the humorous theme along with colour sounds like it could be uplifting.
I had a bit of neuropathy in my fingers and I think Lego would have been very helpful “exercise” for strengthening the fine motor skills!
Yes, I think I need to pick it up again. My fingers seem ok, but perhaps have a slight sensation like they’re swollen at the tips, so doing Lego again would help. I’ve had to hand stitch & hot glue my daughter’s dance costumes recently, so that was a good measure of my hand dexterity. There’s some nice mini plant kits & a cherry blossom set I’ve had my eye on in the Lego kits.
