The sewing thread recommendations laid out above are intended as a guide to aid the construction of items with good quality seams. As items of the same generic type differ in terms of substrate and construction, and both making up methods and post make up processing can greatly vary, these recommendations should be viewed as a good starting point for thread selection.
