So I figured out how to make make up bags this weekend. I don't know where the deep rooted fear came from but I had been resisting this idea for a long long time. I found a great tutorial on Craftster.org that calmed my fears and by yesterday afternoon, I was in business.
The dimensions for the makeup bag in the tutorial were smaller than what I wanted so I swallowed my fear of math and adjusted the pattern to make a larger bag. The smaller one is 7" x 4" and the larger one is 8" x 5". The smaller one is perfect for going in a purse, while the bigger one is just right for holding your daily make up.
