I made this bag with fleece and cotton blends and embroidered it with polyester thread. The stars and moons and unicorn all glow in the dark. The bag has a pocket on the outside and a smaller pocket on the inside in the biggest compartment. This is about 14 inches tall and can hold a lot of weight. The strap is adjustable and can be switched out with another strap.
