It is highly recommended to use a wide shoulder hanger when storing stiff collar interlinings. Wide shoulder hangers can better support the collar and shoulders of clothes, preventing deformation or collapse caused by narrow hangers, especially for clothes with hard collar lining. Hard collar interlinings are usually designed to be relatively upright, requiring a wide and stable support to maintain their shape and avoid becoming loose or losing their original contour after prolonged suspension. Wide shoulder hangers can evenly distribute the weight of clothing, avoiding creases or loss of shape at the shoulders, effectively protecting the overall appearance of clothing and the straightness of the collar. In addition, wide shoulder hangers can provide better support for thicker fabrics and reduce pressure points caused by unsuitable hangers. Therefore, using a wide shoulder hanger to store harder collar interlinings can help extend the lifespan of clothing and maintain its delicate structure and appearance.
