I'm in the final stage of assembling a quilt (photo attached, don't mind the truncated points, I'm kind of new at this!). I'm now realizing that I won't have enough of the main solid fabric to make the backing as planned. Problem is, I can't for the life of me remember where I got it! Been through every receipt and order summary and I can't find it. The "triangle" fabrics were from the remnant bin. In normal times I would take a swatch to the fabric store and see if I can find the same color, but of course it's not clear when that will be an option. I find that blue and green colors are pretty tough to match from the computer screen. Should I put this one in the WIP pile til I can shop in-store? Would it look okay with some sort of neutral color, maybe gray or navy? Thoughts appreciated.
