Adding boxed corners to your Tsuno Tie Bag adds a nice detail and adds a flat bottom to the bag making it sit upright more easily.
Because you are cutting of the the tips you do loose some room in the bag, and you are making the pointy handles a bit shorter.
You can use the excel sheet that comes with the Tsuno Tie bag to customize how much depth you create, and how it effects the other dimensions of the bag. This is a great way to customize the bag to fit a small rectangle sized gift like a small giftbox, a bar of soap or a book.
In the video tutorial I'm going to use a French seam to add the boxed corners which is easier than it sounds and makes for a fancy and clean finish on the inside.
I'll be using the Tsuno Tie bag in the video tutorial, but you could easily apply this technique to many bag bottoms. It's an easy but lovely technique to have in your sewing toolbox.
