Iron your snowdyed fabric, encouraging it to become a square shape.
Fold the fabric from top to bottom, putting the crease along the center line in the fabric design.
Then fold back the top of the fabric at the bottom center, and line up the two patterns. You want the center line to match.
Next you want to check the corners. Again, roll up the fabric on the top to peak at the fabric on the bottom.
When you are ready to cut, align the line on the square ruler that corresponds to half of the size you need, along the center line of the pattern on the fabric. In this case, I needed a 20.5″ square for the center of my Tantalizing 9-Patch pattern, so I aligned the 10.25″ line on the center line of the fabric pattern. Then align a second edge of the ruler along the center fold of the fabric. This should allow you to cut along the edge that corresponds to the 0 line.
Then simply flip the ruler around to do the same thing on the other edge. This will give you a 20,5″ square when you unfold the fabric.
