Circoflex- Hull skyline

I had this idea over a year ago and intended to make it to promote "Hull UK City of Culture 2017" I've stated a bit late but hope to have it flying at the Fuerteventura Kite Festival next month!

This is the full scale layout.
I think it will be a bit of a problem to sew the design especially the Hull Minster in the middle
