The rules are simple: you will make ATCs based on the number four. You can include the number itself, the word 'four' (in English or in another language), the Roman numeral four, four of something... you get the point. You will make three ATCs, one for each partner. ATCs can be any medium, any technique.

This swap is part of a Numbers ATCs series; here are the other swaps:
* Numbers ATC - 1
* Numbers ATC - 2
* Numbers ATC - 3
* Numbers ATC - 5
* Numbers ATC - 6
* Numbers ATC - 7
* Numbers ATC - 8
* Numbers ATC - 9
* Numbers ATC - 0
I will also host one or two make-up swaps at the end, for anyone who missed out on a number or two!

Usually ATCs rules apply: ATCs must be properly sized - 2 ½ X 3 ½ inches or 63 mm X 89 mm. No 'sticker-slapping;' please send something that you would be thrilled to receive.

This swap is open to newbies. However, if you are new (fewer than 10 non-email swaps), please finish your ATC before joining the swap and send me a picture of it (that way I know it's done and ready to go!). Anyone with unexplained 1s or 3s, please message me before joining and explain.

Any other questions, please message or ask below in the comments.
