Book Decoration: AKA All The Ways I Don't Use a Cricut
(this post is for people who don't want to buy an expensive cutting tool, or for those that do have an expensive cutting tool that would like to mix things up a little)
If you're already printing your own textblocks, an easy step for titles is to print them. Above is a title printed onto an "obi" of decorative paper. I measured out where I wanted things on the finished book and laid it out in Affinity, then printed it on a full sheet & trimmed it down to wrap around the book. A more simple method is to print & glue on the label into a slight indent in the cover (to protect it). A third option is to do the spine in bookcloth, while you print on paper for the cover and then glue that paper onto the boards (this usually looks even better when it is a three-piece bradel bind).
2. Foil Quill / Heat Pens
The heat pen is one of my go-to tools, but it can be a bit touchy about materials. The most popular version is the We R Memory Keepers' Foil Quill (which is one of the most ergonomic), but other pens exist that can get you to a higher heat temp, finer lines, or more consistent foil. For example, I have a pen created by a local Japanese bookbinding studio that fares way better on leathers than the WRMK quill & with a finer tip, but it's hell to control. Best results in general are on paper or smooth bookcloth (starched linen, arrestox, colibri - even duo will work but its less solid). The fuzzier a bookcloth is, the less your foil quill wants to deal with it. This means the heat n bond method of making bookcloth does not play nice with a heat pen usually, but there are two solutions: 1) use this tutorial on paste + acrylic medium coated bookcloth instead that will get you a perfect surface for the heat pen, or 2) use the pen on paper & then glue onto the cloth. I did a video tutorial for both foil quill use and this type of homemade bookcloth for @renegadeguild Binderary in 2023.
You get the most consistent results by tracing through a printed template that is taped in place, as I do in the video above.
Acrylic paints will do you fine! The above is free-handed with a circle template, because I wanted that vibe. If you need straight lines that won't seep, lay them down with tape first & then paint over it first with a clear Acrylic medium, then your color. Same goes for stencils. Two more examples of painted bookcloth:
By using layers of thinner boards, you can create interesting depths & contrasts on your cover. You can also make cutouts that peep through to the decorative paper behind. The most important part to this technique is the order in which each edge is wrapped. To get a good wrapped inside edge, you will split the turn in into tabs to get them to conform to a curve. You can also layer multiple colors of bookcloth without multiple layers of board, as seen below left, so long as you mind your cut edges for fraying.
Mirrors! Marbled paper! I saw someone do a pretty metal bookmark once! The key is creating a little home for it to live in, which is pretty similar to the above layering method. On one layer you cut the shape, & glue that layer onto the bottom solid board before covering. You can do the top layer as an entire 1 mm board (like I did for the mirrors) or a sheet of cardstock, like I would use for inlaid paper.
Decorative paper is always helpful & adds to the paper hoard... & its effects can be layers with other techniques, as below. Marbles, chiyogami, momi, or prints & maps of all kinds can be great additions. Some papers may need a protective coating (such as wax or a sealer).
7. Stamps (with optional linocut)
While I've not used many more regular rubber stamps, I do know some who have, successfully! And I've used one once or twice with embossing powder (see photo 3 up, the gold anchor on the little pamphlet bind). What also works is to carve your own linocut or stamp, & then use block printing ink to ink it onto your fabric (as i did above). A bit time intensive, but it was nice how easily reproducible it was, and I liked the effect I got for this particular bind.
These methods are not exhaustive, just ones I've used, and there are of course many others. I haven't gone too into detail on any of these for the sake of length (& post photo limits) but feel free to ask about more specifics. Usually I'm using them in combination with other options.
