There is an awesome tutorial here on how to ruler fold quilting cottons. But if you are like me and have lots of fabrics that are 60″ or more inches wide (not 44″ like quilting cottons) you have to figure out how to make it work. I promise its easy!
First up lay your fabric out nice and flat. This is a 70″ wide fabric and is 2 yards long. I have the 2 yard length left to right in this picture.
Fold the edge closest to you up 1/3 of the width of the fabric
Now fold the top down the other 1/3 of the width of the fabric
Now you can ruler fold. Lay your ruler on the end of your fabric. I like a 6″ ruler for my fabric but you may find a different size works better for your shelfing than the 6″
Fold the end over your ruler
Now keep rolling your ruler until you have almost all the fabric rolled up
It should look something like this
If you are like me and want it really neat you will fold the end in like this
Fold over the rest of the way
Slide your ruler out
Now fold your long log of fabric in half. This is a side view. This is a thick fabric so yours will likely end up thinner.
And this is what you will see from the front
There ya go! You just ruler folded a cut of wide fabric!
