I do this a lot--I like to take my art that I've made in the past and add it to brand new art. In this case, I went through my faces from older art pieces and sketchbooks. I'll find a face, and let it help me decide on where I want to take it.
I print out the face on my computer and then I gather papers that compliment it, and then put them all together in a collage--
This next face was from 2013--one of my favorites--
Originally, this face was done in pastels, and the poppies were created with acrylics. So I took her face and made a new collage--
bringing in the brand new colors and flowers to change her up a bit.
And I also like to go through my sketchbook drawings--
So with these 2 girls, I did something different. I printed them out on a dictionary page--
......and put them on a box....
This is also a great way of taking your art journal pages and turning them into art pieces. You can use part of them or mix them with other pages--the possibilities are endless, and always fun. Plus it helps to do this when you're in a bit of a slump--your old art will help you make some new art--I promise! :-)
