It is a little zippered bag. Currently using it to hold stuff from my pants pockets at night when I go to bed.

All of our class projects use scrap material. I had found the inner material while looking for stuff for a different project. I could not find anything that would go well with it, but I think it does well with this bag as a surprise lining.

Edit: I was asked about the pattern, I got this video from the class syllabus. When opening it while not logged into YouTube I got tons of recommendations for other videos making the same bag.
