This kit is designed to accompany the Redthreaded 1880s corset pattern (sold separately). These kits contain all of the specialty supplies needed for your project. You will need to provide some additional standard sewing notions such as bias tape, thread, and optional outer fashion fabric. In cases where bone lengths vary between sizes within the same pattern pack, all bones needed for each size are included. This may result in surplus boning. Please be sure to choose the correct size pack...
