If you are just starting on your mixed media journey, consider using lace to create beautiful textures on your background instead of creating a background from scratch.
I adhered lace on my 8 x 8 canvas, then added colours with watersoluble crayons. Some PearlEx was added to create a sheen.
Then I added gorgeous vintage buttons from the Zeus and Zoe store. You can see that I couldn't decide which ones to use so I used them all! *winks*
Try using lace for the base of your next canvas...share your link in the comments so that I can come take a look! Cheers, Yvonne.
