Cast a spell on your handwriting with a simple trick I use when I'm unable to use my calligraphy pen. All you need is a marker of your choice. I like to use a fine black Micron pen. It works great on things like kraft paper bags and coffee stained papers.
For Halloween, I'm using this trick to decorate simple kraft treat bags. The process is simple. In addition to a marker, you will need a pencil, a ruler, and a regular mouth jar lid. Step by step instructions are provided in the following video.
