I ran across a video tutorial ( https://www.youtube.com/watch?v=KChUsEJPHqk ) on making a small boxed bag like would be used for cosmetics. The process looked so easy that I jotted a few notes to myself and went right to the studio to give it a try.
As it happened, I had the same fabrics that I had used for this duffel bag (black floral exterior and teal polkadot interior):
What I did not have was more of the teal zipper but I found a raspberry one in my stash so I was off to the races.
The project takes only a 14" zipper, two exterior fabric pieces (8 x 10), two interior fabric pieces (8 x 10), two fusible interfacing (8 x 10) and two tabs (2 x 3).
It uses straight and zigzag stitches throughout and also uses a standard and a zipper foot.
Total construction took less than one hour.
Here are a couple of exterior views
And one showing the interior:
The finished size is about 3 x 5 x 7. This will go in my duffel when I use it as a carryon bag so I can corral my phone, medications and other small items.
