Star Ship Background Doodles

Quite some time ago I produced the boards I use for Star ship games, yet to happen to be honest and it was suggested by Tristan M that it would be good to have a design of some sort in the background to suggest the wall interiors. So since I have been a away visiting my ma and pa, I had a little time to make a drawing of the sort of things I may well use, so here it is:

Instead of whatever surface I was playing on I will draw up some ideas based on the above doodles and use them to cover the areas between the boards. Not sure if it should be on a large sheet or individual bits /lengths yet.
