This is a nice idea but it is NOT FELT! Many of us who are dedicated to making fine handmade felt are unhappy with the use of felting terms to describe things that are not felt as in this definition from Merriam-Webster "1 a: a cloth made of wool and fur often mixed with natural or synthetic fibers through the action of heat, moisture, chemicals, and pressure b: a firm woven cloth of wool or cotton heavily napped and shrunk."
The process described in the article is more akin to needle-punching or could be called needling. The use of felting needles does not make the end product felt.
The reason that some felt-makers are upset with the misuse of felting terminology is that there is some work being produced that is called 'felt' that would fall apart with just a bit of pulling, or would pill with the first use. With true felt the fibers are so entangled that it is impossible to pull apart. For those of us who sell our felt products this an issue of trying to educate the general public about what felt is, and how to recognize a well made piece.
As a former dictionary definer I know how words change meanings; in fact your use of the word here would be put in a file as evidence that the verb 'felt' is changing. However this felter wishes this change was not endorsed by magazine editors.
