The Flat Pouch is a favorite pattern for a simple canvas zipper pouch you will sew again and again. Use the pattern pieces in the How to Sew Clothes book to make a set of three sizes (small, medium, and big) or draft your own by drawing a rectangle shape in the size you want, finding a right-size zipper, and adding extra room around the pattern edges for a seam allowance. These are a great way to practice pivoting at the corners and accurately sewing straight lines.
