It has happened to all of us, you buy a garment that fits perfectly then you wash it and it shrinks. Well that is why I am bringing this topic, to talk to you about the importance of pre-shrinking the fabric before you start working on your sewing project.
It is important to preshrink your fabric, especially when using natural fiber fabrics and blends because they tend to shrink when washed and dried regardless of the temperature used in the washer and dryer. This process will allow you to understand how the fabric behaves regarding shrinking, color running, wrinkling among other things.
What I have learned from multiple sources (books, websites) is that the guideline to pre-shrink your fabric is to use the same method you expect to use for washing and pressing the finished garment. In another words, if you expect to wash your garment in hot water, use the high heat in the dryer and use a medium temperature when pressing it, then you should do the same with or without detergent for the fabric. If it is dry cleaning then have the fabric dry cleaned before you start your project.
When drying, if you are not using a drier machine, lay the fabric flat when drying, this will prevent the fabric from stretching of its own weight when hanged.
Pre-washing woven fabric can cause your fabric to get frayed on the raw edges resulting in a messy mix of knots and strings. To avoid this you can sew a length rolled hem on the two raw edges or fold the fabric and put it in a lingerie bag as well.
Do you have any good tips on preshrinking fabric? Feel free to comment!
