The Trinity Stitch Book Sleeve has 3 different sizes, 5” x7”, 7”x9”, and 9”x11” with an optional button loop closure. The small size works great for smaller books or for a Kindle. The medium size works for a lot of books, and the largest size will work for larger books or even an iPad or similar size tablet. The Trinity stitch worked in the round creates little clusters that make up the body of the book sleeve. The top is finished off with rounds of single crochet stitches.
