When you buy fabric, choose a good quality fabric. Stay away from fabric that are cheap, thinner, has imperfections, and unknown fibers. Cheap and thinner fabric will not last long. If you still decide to buy some unknown fabric, wash it first and dry it in the dryer at medium to high heat. If this fabric shrinks this is the time you want to find out. Don’t wait that you invested your time making the garment to find it’s ruined after the first wash or dry cleaning.
