I created this page in Sabrina Harrison's journal which I bought at a bookshop (she created this journal with background images using her art). It's a good exercise in not being so precious about the backgrounds you create and braving thtough into layered work.
I used gel medium to glue the collage images to the page. Tip: if you tear out the images instead of cutting them with scissors, you get really interesting soft edges that are easy to blend into the background surface. Another tip is to layer images and words so that they touch or even cover bits of each other. Helps the work look more complete and integrated. I added - with my fingers - white acrylic or gesso around the edges and let it cover bits of the collaged images. Finally I added text with my black uni pin fine line pen. It's perfectly fine that you can't see the original background any more or, if you can, you can no longer distinguish it from the compelted work.
