This is a super easy project that you can create using paper sandwich bags, some acrylic paint and stencils of your choice.
25 paper sandwich bags
Metallic paint in the color of your choice (I chose Spun Gold Crafters Acrylic)
Accent paint in the color of your choice (I chose Brandy Wine and Crimson Tide Americana)
First, place your pattern stencil on the top 2/3 of your paper bag. Daub with your metallic paint, I chose gold, and lay to dry.
One your bags are dry, it's time to stencil the numbers. I mixed my two accent colors, Brandy Wine and Crimson Tide, to get a nice rich berry color. Simply daub with your sponge over the stencil and lay flat to dry.
Once all of your bags are dry, hang them with burlap twine using clothes pins. These two materials give a rustic charm to your otherwise classically elegant paper bag advent calendar garland.
