I found this super cheap stencil book with a variety of ideas and patterns in it.
|Using stencils to add interest to an envelope|
|simple collaged postcard from magazine parts|
|I like the color techniques, though I haven't figured out how to incorporate my paints in to the letters.|
|art class: an envelope from NGS magazine|
Anybody have other sources they would like to share?
I think the important thing is to add personal touches you feel comfortable with. If stickers are your medium, stick to it! If pen and ink are your strong points, draw from them! And if random is your method, scatter the thoughts! But I challenge you to try something different and make your letter reflect some of your personality!
Keep inking it up,
