The Coloring Book of Cards and Envelopes
It looks like a coloring book, it feels like a coloring book, but it's much more than a coloring book. Each page can be taken out and folded easily into either a unique card or fun envelope to put it in. I've never seen anything quite like it and it's quite fun. No more generic cards from me.
Even though it's a coloring book, I wouldn't recommend it for children as I'd initially intended. Most of the coloring pages are intensely detailed and would be hard to complete for anyone who doesn't have an attention to detail or a long attention span.
If you have both of those, this is a great way to add a little fun into mundane tasks like sending our cards.
Absolutely stunning art to color and make into a fun project that anyone can enjoy.
