Last year Dad and I agreed to make an artwork together. sending insructions to each other seemed the most practical way of working as I live in London, my Dad lives in Stockport.
We started with the same size piece of board and decided we would send an instruction each month.

We agreed some rules; we would send a photo of the work we had done before worked out the nect instruction, we would send our instructions on the same day and make sure we didn't read the others instruction before sending our own.
