The last grey fabric I tried to sew with proved impossible to colour match, so I wasn’t hopeful about finding top-stitching thread to go with my current project. The fabric’s a grey denim and I wanted top-stitching thread in the same shade for a subtle effect. I haven’t been able to make it to a physical sewing shop for a while so I crossed my fingers and ordered Gutermann Sew All and Top Stitch in shade 036 online; a colour variously described as “light black”, “dark grey”, “grey”, and “charcoal” by different vendors. And lo and behold it’s almost a perfect match. Funny how these things happen.
