I had everyone pick a spread...(two page that open up next to each other) and use some found papers and book pages..I had them glue down the papers in any which order and over them them too.
Now you see the page is cut out already as of a big circle on both pages.. that can be done after you glue about three pages together then cut the shape out and I make a few spreads like this and move that hole over just slightly...so you can see through the next spread. Not everyone did this it was an opinion..
Working with an art journal is very intuitive...follow the flow and listen to your gut.
I have some deli sheets between the other pages in the journal so that the colors and gesso don't get on the other pages. A house stencil from the shapes I cut out of the magazine cover...from above.
