I usually make layouts in two steps, first I use stencils and then I color the background - on a white cardstock. I drop some mists too. In the example underneath I have used a Silhouette to make my own masks and used Distress ink for the patterns.
Then I might stamp some too. Another example.
Then I focus on the layering. After I have made my choice of paper, fabric and other I staple it together leaving lots of air between the layers, then I add more in between like ribbon, border punches paper and washi tape. Then I finalize with some details. This is one of my layouts using this type of layering. I also crunch the papers a little before I staple them together to give them more air in between.
Then there is another type of layering that I am not that familiar with. The type of layering where you adhere everything to the background and add for instance gesso and stamps on top of the layers, which is easier than in the first example, because even though its full of layers - it's flat. You don't have the same amount of freedom to add stuff inbetween though. I made this layout in very poor light so hence no progress pictures. Just table lamps, but I guess you get the picture of how its made. I used tape, glue and gesso to adhere the paper to the white cardstock. And since it was flat - I stamped on top.
