I made this drawstring bag for my friend recently. When I sewed this bag together, I had to make it in a hurry, and as it turned out, I was able to make it in about an hour. The bag is reversible and it is made based on the great tutorial from Pink Penguin. The inside looks like this.
As with any other handmade gifts, the most difficult part for me was selecting the fabrics, but the recipient seemed to like it (which made me happy :)
