Through a combination of cheap acrylic yarn* (Red Heart Super Saver) and my dreadful sewing skills, this looks dreadful in real life. Ah, well, I tried. There's no pattern because it's just single crochet folded in half and I used decreases to make the flap.
*Super Saver is fine for amigurumi but I hate the way it looks in purses, clothes, etc. Maybe I'll try cotton next time.
