Handpainted Barcodes

I have recently been playing around with a few ideas for the final project for Textile Art and have sketched examples in my sketchbook. The latest idea for Marks in the Landscape involve the bar code as I'm using the economy and social attitude and mood of the country and landscape for my final piece.
I have painted these barcodes using heat sensitive fabric paint which I bought from HobbyCraft. Firstly I attempted to create a semi decayed/rusty/mouldy background and then painted the bar code over the top. These pieces will now need to be ironed so as to bond together the paint with the fabric.
