One of my friends was going to start playing with ATCs and after getting some goodies at That's Not Garbage the other day, I thought I might as well have a bit of a play.
They were quite fun, and pretty quick to do, although I can see how you could spend a lot of time on them. Seeing all the ones on craftster I didn't quite realise how small they were when you're trying to put stuff on them, but I think that's a good thing because it focused me a bit.
The one on the left is called 'Disco Amoeba' and was just one of those pictures where you draw randomly and then colour in the different areas (other people did them at school didn't they?) and the other one is called 'Woven Tree' (I was out of ideas for names) and is two different patterned papers woven together, with a tree and bird drawn on top. It's actually done in gold ink which is more gold in real life, although the design is still quite subtle.
I think these are quite good for little projects to inspire creativity, because you can spend as much or as little time on them as you want and you come out with something finished that can be anything you like.
