One thing you should always keep in mind is to analyze the fabric you are choosing to make a curtain or a curtain. It is important to prepare the fabric too. In some cases, as a beginner, the seamstress cuts and sews the curtain or a curtain for the windows, but when after a while they wash it, it will shrink and its measurements will be wasted.
I recommend following the manufacturer's guidelines. Some people like to sew the curtains of the net, while others like to prepare curtains of thick material. In this case, you should ask the person about the fabric when you buy it or always wash it before starting your work. It is necessary to iron the fabric so that there are no wrinkles at the time of cutting.
Due to wrinkles in the fabric, people stretch and when they finish the cut, they realize that it is not a straight line. This is going to be a great disaster for you when you start working on any project
without analyzing the type of fabric you are working with.
