The Incredible Shrinking Comfortor, Blanket or Bedspread
Some natural relaxation shrinkage can show up. There is usually a fullness of the backing or shell fabric, causing a puckered appearance. Also any piping borders, quilting stitches and seams may be rippled or distorted.
The major cause of shrinking has to do with the original fabric not being properly preshrunk or stabilized before the article was constructed. Some slight shrinkage (about 2-4 %) is to be expected on all household items, but on properly cleaned items that shrink excessively, the manufacturer should be held responsible.
