It’s actually very easy, and it’s easy because it just involves a sewing machine and a regular pair of clothes. All you need is at least two pieces of the flapping fabric. You need to cut at most eight pieces, but if you need more you can fold a flaps into a square. The fabric you need is called a flap. In addition to the stitching you will need a seam allowance. There will be a seam allowance for the top edge, but not for the bottom edge. You will also need a seam to separate the two pieces of fabric. The only reason you need a seam is so the top edge of the fabric will sit on top of the bottom edge of the top half of your flapping fabric.
The picture on the left shows the process of how to sew the two pieces of fabric into a flap. The picture on the right shows the finished seam.
If you make the top and bottom pieces of the flaps like I do, you will have the seam allowance seam, while the upper part of the fabric will go on the bottom. Here is a picture illustrating this.
This picture is taken at the point when the seam was made.
I would like to point out that this is much easier than it looks because you don’t need to stitch on the flaps to do this. So the flaps are not part of the sewing process, only the seam allowances on each seam are done during the sewing process.
It’s also important to make sure that the flaps are very straight. That’s because they will be sewn on for all three layers of the dress. So they need to be able to have a straight edge.
Here is an image that shows how the dress is designed for the seam allowance seam. If you look carefully at the seam along the seam where the top and bottom were sewn on, you can notice that the seam is not perfectly straight.
The seam is also curved in a way that you will not see.
Sewing the Flaps
Once you have made two layers of the flap, the front and back layers and your seam allowances are assembled you need to sew the flap for each layer.
This is going to be the part where you must choose the seam allowance. There are lots of places where you need to choose the seam allowance. If you want your flaps to be tight as they are in the picture, use a seam allowance that is wider than 1/
