Whenever I'm feeling the urge to make something but don't know what to do or I don't want to get into anything too complex, I collage scraps. Collaging cardstock packaging with painty papers, random scraps and spent art tissue for what I'm now calling my "Background Book", is a go-to no brainer I find completely relaxing. These will eventually get some further stenciling, stamping and/or random painting. I might use them for journal covers or possibly cut up for tags and journaling cards...who knows?
Junk Journal ephemera: I have an excessive amount of scrapbook paper that I'm trying to find projects for. These are the cut up strip pages that are included in many pads. I mash them up, layer 3 different widths and then do a decorative stitch down the center. These can be used as belly bands and then remnants of those belly bands can be used in clusters.
