I make triangle shaped labels for all my quilt projects. This way I can stitch them to the quilt on 2 out of 3 sides. I usually use steam a seam to tack down the last seam but if left open you could use it as a pocket to hold something. To make my triangle label I take a square piece of fabric and fold it diagonally. I usually add my words using my embroidery machine. Have a template I made in my Embird program and just add what I want to say within the outline then skip the 1st color (outline).
