I made my own wrapping paper for xmas this year. I think it came out a bit more bonkers than I expected but it was heaps of fun doing it. I made a huge mess and got paint everywhere. It was just regular acrylic paint, diluted with water and splashed on with sponges and brushes. If was to try it again I might try a bit of restraint and maybe choose a colour scheme instead of going totally nuts with all of the colours. I say that now... but actually... it's unlikely!
