Made a Birthday card for my Sister

I know you can buy birthday cards but to me they seem impersonal, and as im not really buying my sister a present i decided to make a card

This is what the front of the card looks like:

These are the words i added:

Sisters annoy, interfere, criticise, are always underfoot. But if catastrophe should strike sisters are there. Defending you against all comers.

Sister to sister we will always be, a couple of nuts off the family tree
