My herbarium is coming along between treatment proposals and lecture writing: I chose really beautiful handmade paper made by Chris Petrone of the Womens' Studio Workshop, with nonpareil marbled endpapers from Payhembury. I dyed Pergamena vellum green for the tapes. I've worked on a few green vellum account bindings and the color is really satisfying. And then I took a last look at the deckle edges—lovely but uneven & difficult to turn—and plowed them right off. I found immense satisfaction in putting the trimmings in my vermicomposting bin, though! The worms will eat them, which enrich the soil, which will grow new plants, which will become pressed specimens for the herbarium. It's too perfect.
I wasn't sure what to do with the head edge, and colored it yellow with gamboge first, but on second thought rubbed some Prussian blue in and made them the same green as the vellum supports. More or less exactly the same green. That was pretty satisfying, and with a little wax & burnishing they're super shiny. Endbands are green, blue-green, & a pale blue over alum taw & vellum cores. I made the vellum long to lace it into the case with the sewing support slips.
The next step is done, making the case Bradel-style, to be covered in white vellum. I was planning on making it go transparent by soaking it in potassium carbonate & pressing hard, à la Edwards of Halifax, but no matter how I've tried to do it, I haven't managed to affect any change in the skin. Plan B has just come to me in writing this, though, so stay tuned for covering & lacing in.
Now, if only the sun would stay out a little longer, & get my plants growing faster...
