This carp fabric is based on my carp collograph.  It was inspired by a pond of carp we saw every day while on holiday in Portugal.  The repeat size is 20cm x 20cm (8x8in).  You can read about the collograph process here - it is a fascinating technique which produces rich, detailed results - depending on the inks and colours you use, it can also be unpredictable!  You can buy it from Spoonflower here.
