I'm bringing you a fun tutorial! Be nice to me because I haven't done too many and my workspace doesn't have the best lighting for pretty, pretty pictures, although it IS functional.
Making earring cards doesn't have to mean being a professional graphic designer or having them professionally printed, although that would happen in a perfect world with limitless resources. Sometimes, you need something on the fly and this is a good quick fix. I think they have a nice presence, don't scream ugly, and reflect the quality of handmade work.
One of my pet peeves, having a background in graphic design (archaic as it is) is seeing pretty handmade goods on crap-tastic Avery perforated business cards with badly done graphics that are all pixelated. Yuck....
And, in saying that, I bring you this tutorial from a place of love.
Before we begin, let's talk about some basics of package design:
1) KEEP IT SIMPLE. If you don't have the knowledge or resources to have something professionally printed, don't try to make your packaging look like you do.
2) Stick to one or two colors and one or two fonts. More is not always better.
3) Keep it clean. Don't clutter up your packaging with too much information.
Let's get started:
(Remember you can click on the photos to see them better.)
Make sure to use a nice heavy cardstock, not plain from the office store. Make sure it is at least 90#. Scrapbook cardstock is a good fit or if you plan on making a lot, you can order a ream of heavy cardstock from a professional printer
I chose grey for the background and black for my letters, sticking to my KISS rule. 
Hope you enjoyed my tutorial! I would love your thoughts! (ummm, good and bad, :)
