I know how to clean, but need more help ?

Blocking is just the technical term for setting the final shape and form of items such as knits and lace, and is often used with sweaters. blocking adjusts the shape of the finished piece. blocking really only works on natural fibers, but the term can be used like in this case to describe carefully positioning the garment in a specific manner. You can replace the word block with carefully place over a hanger ...

I would lay a towel on the table & place the sweater flat on to the towel. most items such as these need to be flat dried

means fold it in half on the hanger. So its drapped.... come on im 17 year old teen and i know that
