Above you will find some of the book covers I use for my easy balsa books. Once you click on the image it will open into a new window. Just right click and save. You will need to adjust the size. The image once saved will be very large. I make the largest one here around 2.5mm. But it is a personal choice. I print them on a better grade of A4 paper on high. Then spray over the printout with matt spray. Let that dry and cut them out. Then I 'rub' the unprinted side over a glue stick (Bostick)and glue them over a strip of balsa. Thickness of the balsa will depend upon the size of the book spine. Get it as even as possible so the the halves match up. So that when you trim away the excess balsa you aren't taking away too much of the printie. Let the glue set itself. Trim away balsa and lightly sand if necessary. What you do after that is a personal choice. I like to run a round needle file along the longer page edge to give it the curved look some old books get. I sometimes then scratch in lines with a embroidery needle to give the appearance of pages. I like to make mine old cause well they are. These book covers are all at least 100 years. Some are from the Art Deco period. Old!! I go over them with my dirty brown wash and wipe away or dab away some of the excess. I find sometimes the printie comes away from the corner of the balsa which I like as well. Gives it a dog eared used look. That's pretty much it. Hope you have fun!
