Knitting, Crochet, etc. Related Overlays

I have a character who is a yarn crafter. I’m having the hardest time finding overlays. Stuff like knitted projects in progress, a basket of yarns, that sort of thing. Anyone either know of someone who makes that kind of stuff or is willing to make it?

The other day I asked where to get Piano overlays and someone pointed me in the direction of this website called PNG tree. It is really useful.
