here is the site that I got all the patterns from, they are FREE.

this site also has other PP patterns.
The wildest part, they are not in English. But, if you can do the old paint by number kits, you can do these.
As for if it's easy. Yes it's really easy. When I printed them out, I printed only in black ink. It saved on the color ink and I didn't want the same colors as they showed. I found some more NYB blocks, but, since I can't read anything on their site either. I emailed them. I guess I will have to wait and see if they can read english and email me back.
