As usual the first thing is baste it. We create a roll from the fabric and then baste it down and sew it. 

To create a roll take the edge of skirt and fold it once. The folding should be about one centimeter wide. If you are not confident enough you can baste it in this part, but it is not necesary.

Then take the folded edge and fold it second time. The edge will be completely hidden inside of the roll this way. 

This is the time where you should baste it so it won't slip away. Make that roll around the edge and make sure that the hem will be 1 centimeter wide everywhere. 

If your hem has not the same width everywhere do not copy hem's edge but sew along the carf that is on your sewing machine. Set the fabric to go along the 1 centimeter carf and move it along, so that the stitches will be in the narrow line.

Hope this one helped,

After you cut out your waistband you baste it to the front of the skirt. Remember that front side goes with front side.
Important fact:
Always baste it on front first because you want the parts that are showing to look the best while the parts that are not showing do not necesarilly have to look the best.
 After you flip the waistband it should look like this:

After you have that basted sew it normally with classical stitching. With front part sewed press the sewing in the middle so the stitching will look the best.

Baste tthe back part to the front in the way that the back will cover the stitches as it is shown on the picture below.



Then sew it and press it.
Haute couture tip:
To make the waistband look the best sew it front side up and through the stitches that are joining the waistband and the skirt. This will hide the stitches used to sew the back of the waistband and it will not be seen on the skirt.
 You can see that needle copies the stitches used for sewing the skirt(on the left) and the waistband (on the right off the picture).

You can press it to make it look better.
In the end you have only sewing the button and button hole left.

Button hole
You can make the button hole without sewing machine with a specific stitching but that is too difficult in opposition to using the special presser foot for buttons. It looks like the one on the pictures below.
The priciple is to put the button in the back of the press foot and then the sewing machine does the rest.


That's all, hope this tutorial was helpfull.
