I've been seeing sewing frames for bookbinding in a lot of bookbinding books and on blogs of bookbinders. I started to look around for one and the prices varied anywhere from $45 to $125 dollars. Since my husband can just about build anything, I had him look at a few online and he figured out the mechanics of the frame. For $15 in material, plus his labor, he made me a very nice sewing frame.
To hold me over until my tape keys and more linen tape arrive, I used blue painters tape to hold the linen tape on top and bottom.
The drawing journal I made measures 7"L x 9"W. I had 5 signatures with 4 sheets of drawing paper, giving me 80 pages to use.
