A typical music cassette stores about 300 feet of tape! Sadly, I have probably trashed miles of tape over the past decade. Sound artist Alyce Santoro held onto her mixed tapes and invented sonic fabric,a textile woven from 50% cassette tape and 50% polyester thread. You can actually listen to the sounds embedded in the fabric! (Here’s how to make a sonic fabric reader from an old walkman.) Check out these sonic wears.
