Today we'll be working on an 8 1/2 x 11 inch piece of paper.
1. Give it a 1/2 inch border all the way around. Turn your paper so it is the tall way.
2. Place your ruler horizontally across the top of your paper. Make a very slight mark at 4 1/4. (1/2 WAY ACROSS THE TOP)This is the original mark. Next, mark tiny lines an 1/8 of an inch on both sides of that original mark.
3. Do the same thing on the bottom of your paper.
4. Turn your ruler vertically and connect both of the marks 1/8 of an inch from the original mark. DO NO CONNECT THE ORIGINAL MARKS! Now you've got two panels with a gutter between them.
5. Keeping your ruler the vertical way, mark 3 15/16 and 7 5/16. These are the original marks. Then mark an 1/8 of an inch on each side of those original marks.
6. Do the exact same thing on the other side of the paper.
7. Connect the marks, EXCEPT for the original marks at 3 15/16 and 7 5/16. Now you've got 6 panels with gutters.
8. If you want to get creative, you can change one of the square panels into a circle or a star. Or you could tilt one of your panels, etc. Just keep the gutters consistent.
9. Ink your lines, using a ruler.
