Here are just a few pages from the 5 Mixed Media Collage Journals that I've been working on for the past 3 years. I love mixing different 2D drawing materials with paper clippings, drawn illustrations, and paint. This might seem like I'm writing a romance novel for art nerds, but something about the way that oil pastels sit on top of acrylic paint and watercolors is just so rich and creates these beautiful textures. I mean, I love to make digital artwork, but the materiality of physical mediums on paper is so satisfying!
My 5 Mixed Media Collage rules to keep in mind:
1. Oil based products have to go on TOP of other materials, because the curing/drying time is different. If it goes underneath other materials, it compromises the archival quality of the work (meaning it won't hold up or dry properly).
2. Pens, charcoal, and other dry drawing materials have a hard time sitting on top of Acrylic layers because the paint's plasticity is not porous, so it will not take in the dry drawing mediums (such as any charcoal, ink pens, pencil, and pencil crayons). IF you want the marks in your work to have archival quality (meaning that they will last for many years without fading or rubbing off), seal them in with a spray sealant or a matte/gloss acrylic gel medium(with a brush or a palette knife).
3. Watercolors should be done FIRST because they will not sit on top of collage pieces or the binding agent (glue or medium used to adhere the pieces).
4. Layers are good!!
5. Don't try TOO hard- go with the flow! Mistakes can sometimes be made more awesome than you might have planned!
