They actually help with my anxiety, as a distraction but a distraction I can focus on if that makes sense.
As for money, yup, some are new. Many are donated (
@YvonneBlue has given me some lovely ones, plus my neighbour who has given me the same jigsaw on two occasions...twice, lol). Then sales - I just got two 500 piece jigsaws for £3.75 each, along with two 1000 piece jigsaws for £4.25 each. £16 total for four. The trick is to find an image you'd want to create.
And now I have decent windows and can do these things with good light I no longer have to share my desk with a computer. But I do them for fun, I try not to race through them. The only bit I struggle with is getting them started. I hate that part, it takes me almost as long as the actual puzzle does.
