This is my architecture quilt.  A few years ago I was in Zaragoza and photographed tiles on a building.  I always meant to do something with the idea!  Some white cotton was dyed with Setacolour transparent and the colours were just what I wanted for the tiles. Rather than iron for 3 minutes I put the fabric in a plastic bag in the microwave for 3 minutes.  It worked!   No dye came out after washing.........so 'Zaragoza Tiles' came about.
