The world of public domain is very very sticky indeed. Especially when it comes to creating small pieces of work for sale on Etsy.
I must admit that until I started selling on Etsy I didn’t really think about where and how I could use brushes, vectors, layers and fonts. Now, I could spend hours (literally) searching for public domain elements for my banners etc.
So if you check above there are sub-pages for each set of different resources, I’m just going to try and add areas where I find these public domain resources. Share and share alike I say 
Please note that I won’t be adding screen shots etc. – I don’t really have time for that – but I’ll try and be as descriptive as time allows!
At the moment (due to my restricted funds) this page is for links to ‘free’ public domain resources – however – if things take off – then I’ll add a page for awesome paid for PD resources!

Below are a list of websites I regularly visit for resources in the public domain if you’re after general resources all in one place!
Keep Designing.com - mainly vector and Illustrator resources but is great nonetheless.
smashingmagazine.com – I LOVE this website – freebies, tips, tutorials – wonderful resource
Bittbox – more wonderous freebies – brushes, layers, textures etc. YUMMY!
Very interested!
