I've been experimenting with different techniques, and I have some tips to share.
First, let me expound on the versatility of vinyl. I do not have a Cricut or Silhouette, so I can't cut out vinyl letters or shapes like other crafty folks. However, I DO have a Big Shot and Stampin' Up!'s awesome dies and framelits.

I bought a roll of white vinyl at a craft store in town, and then ran it through the Big Shot with the Star of Light framelits. I then placed the vinyl stars on plain ball jars and painted.
Here are some of the materials you'll need (I forgot the vinyl or the very important Mod Podge).
