Bone casing tape is a woven tube into which you can slide corset bones, after the bone casing tape has been sewn onto the corset. This is the best way to hold corset bones in a corset. Alternatively there is "Prussian Tape" which is a tightly woven twill tape and not a tube; it creates a minimal bulk bone casing.
