Geek Craft: Cassette Tape Wallet
The 80s kid in me is quite a fan of these cassette-tape wallets , but at $43 each, it would be well worth butchering one of your old tapes (pick an embarrassing artist you'll never listen to again) to make your own.
And that's exactly what Chezlin on Etsy has done. After splitting the tape in half, she's simply glued on the lining material, and fastened it all with a zipper. You could probably pick a more excitingly coloured tape, but apart from that, it looks much like the "reel" thing!
