A booklace is like a necklace for your book. The decorative beaded part goes on the outside of your book. The hand braided elastic goes on the inside of your book. You can drop the book, put it in a suitcase, backpack, purse, whatever, and the bookmark will not fall out and lose your place. I make all kinds to suit all preferences and styles, and if you have something specific in mind feel free to contact me. I can do commission work on request.
