How to Make a Triangle Bag

How to make a triangle bag

I came across this free pattern on the Bernina website and thought it was a cute handbag pattern to share with you. I like to cal it a triangle bag but they refer to it as an origami bag. Either is correct I suppose. This is a super simple bag to put together. It requires very little sewing but has a great look. This bag is all about the folding. I love making handbags so if you would like to see more of my handbag projects head over to my handbag page and check them out.

I used standard cotton fabric for this bag but you could use wool, denim or felt if you like. This bag is good for many types of fabrics but if you are using a light weight fabric like me I advise to use some interfacing in it. I used fabrics that I had on hand for my bag. The fabrics were purchased at JOANN Fabric & Craft Stores but you could head to or to get what you need for your triangle bag.
