In the past year or so I have been wrapping my fabrics on 8 1/2 x 11 inch comic book boards. They are acid free and can be purchased at a comic book store for about $10.00 per 100 boards. So far I have used over 400 boards and have wrapped many, many yards of fabric.
This stack is the latest bunch that I wrapped, It really helps to keep things organized. I love the way they look all nice and neat in a book shelf. I will take a picture of the bookshelf and add it when I get time. Now I just need more bookshelves or less fabric.
