Lately mustaches are everywhere but on people's faces. I cut the neck out of a plain t-shirt and sewed the raw edge. I found a few mustache silhouettes and used those as patterns and cut them out of felt and hand-appliqued them to the shirt. Oh, you haven't heard of appliques? It's probably because they're so underground... ;{D
I used plain boring T-shirt which was free from a magazine and used felt applique to make it more interesting.
