Local DIYer Kym Bixler figured out a great way to tap into your musical nostalgia while leaping headlong into the future. She takes old broken cassette tapes from the '80s — Cyndi Lauper, the Police, the Thompson Twins, to name just a few — splits them open and sews a felt lining inside. Then she adds a zipper to seal it up, and presto: a retro case that perfectly fits most smaller iPods. Of course, they can also be used as wallets or business-card holders, but nothing says hip like earphones emerging from an old tape.
