I have lots of pieces of art that I have done when trying a new technique or a new tool or medium or stamp etc. I call it my experimental stash.
I gessoed this page in my journal that has kraft coloured paper and did some painting and stamping layers for the background. I chose several things from my experimental stash to create this page. I then did some shading to make the objects stand out from the page.
Have fun experimenting with your stash! :D
