Since I don't own enough bags (ha!) I recently went on a little bag making kick.
These were inspired by this bag made from a pillow case. My versions were made from smaller pieces of fabric so the tied handles were replaced with a button (not even a button hole - just sewn together due to sewing laziness!).
Not the most secure bag, but I like the size and it tucks under my arm well. Good for adding a little colour!
