This is 3.5 hours of stitching time on the bargello (40 count, two strands DMC floss). Not too much more for one complete bench cover. I could in theory remove the stitching to make sure it works before doing the other, but I would have to patch the linen with fabric and re-frame it. Considering the minimal amount of time investment, I will likely just stitch both and hope for the best. I have an idea in mind if it's slightly too small, but I don't think it will be. I am stitching an area with an 1/8" border around the seat insert.
