The camo fabric is from a pair of curtains, Jonathan did try to claim them, but I've kept them for the quilts. They weren't quite big enough to fit the backs, so I've pieced four borders. The border fabric has also come from curtains, this time, plain blue cotton.
The backs are now ready, and all being well, I should be able to bring the backing to the front for binding.
The batting has been ordered, and as soon as it arrives, I can start sandwiching the quilts together and decide on the quilting.
