|I frequently have the problem of not finding a good match for a topstitching thread. Unless I am sewing black or white or want a contrasting thread, the selection of topstitching thread colors are very limited. However, I can usually find a good thread match to the fabric for construction of the garment I am sewing. What I do to match the topstitching thread is put two spools of regular matching thread in the thread holders and thread them separately through the machine. This is not quite as heavy as regular topstiching thread, but it does show up better than just a single thread.
Sometimes I am too much of a perfectionist and the color I want falls between two thread colors. So I buy both threads for topstitching. They tend to blend into the color I want once I stitch them on the garment.
