How Do You Unshrink Rayon?
Unfortunately, rayon is a delicate fabric that cannot be stretched back to its original size if it has shrunk. It is important to always follow the care instructions on the garment label and never expose it to high heat or agitation in the washing machine. One option could be to wet the fabric and slowly stretch it out while laying it flat to dry, but this doesn’t guarantee that it will return to the original size. It is best to prevent shrinking in the first place by taking proper care of the fabric.
