I'm slowly using up every scrap of paper in the house in my book experiments. This includes the cardboard backings on sketch pads, old half-used notebooks, junk mail, etc. I can practice various stitchings without fear of wasting precious materials. Today's book has orange accordian-pleated inserts to close up the inside gaps between signatures. This also adds a jolt of color to the spine and I like the effect, but it makes the stitching very tedious. I don't think this will be a permanent part of my repertoire!
Another thing I tried today was to jazz up the stitches connecting the covers to the signatures. This part was fun, and I can see opportunities here for more exploration.
