People don’t make mixtapes and listen to them on a Walkmen while walking around comic conventions anymore. Maybe you still do as cassettes are making a comeback.
Here’s the 21st century way of creating great looking j-card to match your cassette recordings. The simplest way is to create it is using a free online j-card template maker tool at gitlab. Just type in the cassette title, songs on each side and then pick an an image to use as album cover. Print it out straight from the browser. After that, you’ll need to do some minor cutting and folding. But it doesn’t get any simpler than this. Enjoy!
