I wanted this.
I had this.
So I bought a pad of canvas paper 18" x 24". I used the canvas to make one of those book covers we made in junior high. Remember? I wrapped it around the closed book to get the measurements, (make sure you measure it with the book closed) then cut everything so that the margins were 1 1/4" larger all the way around. Fold the long sides first, then the short ones. Check to make sure it fits. Measure the spine then cut slits in the borders on either side of the spine as shown above.
Each parchment book I saw had 4 ridges equidistant along the spine. Since mine was 10" high, I turned my canvas over to the right side and made pencil lines at 2", 4", 6" and 8". Take a hot glue gun and cover the pencil with thick lines of hot glue.
Cover the outside of the book cover with matte Mod Podge, then lay on a piece of white tissue paper, using a paint brush to tap gently around the hot glue lines. Carefully press the tissue down on the canvas. The tissue may tear so you may wish to repeat the process with another sheet. Fold the excess tissue over and glue it to the inside borders, cutting away any extra. This gives a leather-like texture.
Mix a small amount of yellow ochre acrylic paint into a generous dollop of white paint and cover the tissue paper. Paint the borders and edges as well. Lightly paint over your cover with a dry brush of slightly darker ochre paint to give a mottled leather look.
Slip your book into the cover. I found it necessary to use hot glue on the corners of the book cover to keep it on the book.
For another rendition, add some text to the front and/or back covers. Download this old document here. Print, then copy it on a toner based copy machine as the computer print may bleed when you put Mod Podge on it.
Mod Podge the back of the document. I find an old credit card used as a squeegee, insures that the entire paper gets covered evenly in glue. Carefully put the document onto the top cover about 1 1/4" from the edge of the spine. Use the credit card to press it down. Open the book and glue the paper to the borders, cutting off any excess. Paint the whole cover with Mod Podge to protect it. Wax it for more of a leather look if you wish.
Now who would know that this was just a beaten up old dictionary and not an expensive antique parchment leather first edition?
