Linen Box

I have been thinking about making this box for a long time, so I finally took some time and made it. It was a very quick project and not complicated at all. I could not decide to make it because of the square corners. I just keep thinking about a square bag that I made long time ago and did not go very well. But this time I did my research and I figured how to sew corners (especially when sewing 2 pieces together.)
I have been sewing since I was a little girl but I'm still learning.
I used a floral fabric and linen for the outside with a cotton lace as a detail. For the inside I used heavy canvas to give it some stability.
I am thinking on making a tutorial for this project.
