Having said that, I've stuck with Tilda and as it's back to school for most kids today here in England, I thought this would be apt :)
I just love this Tilda and had to get her as as soon as I saw her but have only just got round to using her! Do you like how I coloured her pencil in her pocket, haha. The desk and Tilda were cut out seperately and coloured with promarkers then just stuck on top of a bit of scrap check paper and piece of paper made to look like torn out of notebook. Tilda has been curved and stuck on with 3D foam - I really like my ATCs to have texture and dimension, don't know why, just do!
Now, I know some people don't 'get' ATCs in that they don't seem to serve any purpose. Well, they are supposed to be little works of art (3.5 x2.5 in size) which you swap with each other (kinda like a business card I suppose and also fun way to see each others techniques, style etc)but as we don't all take part in swaps I think we are put off by that.
However, you can use them as card toppers, tags, or anything else you can think of (as some of the other DTs have shown this week). I could turn my one into a card for a teacher or student.
Personally, I just love the freedom of them not having to be anything, IYKWIM and find it a fun way to get my creativity going. I like trying to make little scenes or sometimes just use lots of scraps for a collage effect. It just depends on the theme and my mood - thay can be as simple or complex as you like and as they are so small don't take long to colour in/put together (mine took about 20mins whereas a card can take me hours, but that's just me!)
