Have you considered www.OpenClipArt.org ?
I hadn't, mainly because I hadn't heard of it before :D
It looks like a great resource though, so thank you :)
Unfortunately, the chances of me learning to draw are slim. I can draw a passable doodle if I can get my head in the right place, but as I said in the post, my imagination is awful. I can't picture things properly, so can't get a mental image of what I want the thing on the paper to look like. I'm waiting on a diagnosis of autism and ADHD and possibly aphantasia. Trying to get things down on paper is very difficult for me.
