Double yellow lines?

Too dark and wet to take a photo outside, and as the patchwork is now approx. 74 in square, hanging it over the front of the wardrobe was the best I could do for a photo, hence only part of the design is visible. The centre, with the Celtic fabric roll, seemed far too lovely to keep at just 52in approx. so I added the gold and red 'crackle glaze' Makower print for an extra 7in border - luckily, I'd added the end of a bolt (just 63in of it) to my stash when I taught in Inverness last month and it coordinated with the Fabric Freedom gold prints perfectly. I am trying to work out what to use for the backing - there are a couple of potential prints in my stash.

Next, the cornerstones for the taupe sampler...
