This tutorial is suitable for beginners who have just started trying themselves in scrapbooking and are not skilled enough yet.
When I was just starting to create, I faced this problem. How to sew a rounded corner of the cover smoothly and efficiently? This can be done manually by turning the wheel of the machine with your hand. But to make an even smoother transition, I came up with this option.
I took a small piece of scrap paper and rounded one corner. Then glued masking tape on it.

Getting directly to sewing, I apply this stencil to the corners and sew directly around the perimeter of the paper.

That's what comes out in the end. A circular area with smooth stitching. Simple and fast. Most importantly, comfortable. Some time ago, this mini-tutorial helped me to make my work neatly.

I hope this tutorial will be useful for you!
