For over half a century, this collar interlining has been the number one choice in sewing workshops. Of course, it's made of genuine linen, but its most notable feature is that it's easy to work with. You can iron it to shape the collar, fix it in place, and it doesn't revert to its original shape even when it cools. Furthermore, it's easy to insert the needle when hand-stitching, thanks to the high-quality material woven with just the right density and tension.
