Most 9 patch blocks (or any block with uneven numbers) can be drafted out easily and quickly to a measurement that is not easily divisible by a given number.....a 6, 9, or 12 inch block is easy to divide by 3 but what about an 8" block? I will show you an easy way to divide any size block evenly.
Here is an 8" block that I want to make into a Monkey Wrench. What is the measurement for a 9 patch? I don't know and really don't care.


By extending 2 lines on your paper (shown here in green)

Place a ruler with the "0" on the bottom left corner, place the ruler on your extended line to the next highest number divisible by 3. Which in this case is 12.


Do the same thing with your other extension for the cross measurements.

Here is the one I made in 8" x 11" size for our guilds BOM (block of the month.

I hope everyone has a great week.
