These bones can be sewn through and are great for making unique shapes, but not for supporting a body in a corset. They come in various widths and the end caps can be sewn through too. Remember Rigelene, this is just like it. Use it to make the under structure. The little rubbery caps are perfect for finishing the ends of these bone, so that they don't poke through fabric. No need to melt or bind the ends!
