The 2nd lot of designs are great, you can not go that wrong with b+w. The 1st design on the last row is my personal favourite.
thanks sam :) i'm so bad at making decisions
the first lot, the debra that is most colourful is my favourite.however i do like the black and white d and n's. espically the one where the n is in the d, second from top furthest to the right. i feel that it's simple and eye catching.
I think the D and N ones are the most successful
