When I was first learning to sew, I liked to make pencil cases and clutches, mainly as a way to practice sewing zippers. My pencil case is simply a rectangle that measures approximately 7" x 4.5" I used a plain black brushed cotton for the exterior and a fun silver quilted fabric for the interior. Prior to sewing the interior and exterior layers together, I applied my iron-on Hello Kitty appliqué that I had purchased in a pack from H&M in the kids section.
Sewing these little bags are a good way to practice inserting zipper and an excellent way to use up spare fabric. They also make excellent gifts because they can have many functions other than a pencil case, such as a clutch or a make-up bag. A pouch this size also fits nicely inside a larger purse.
