My fattest long ruler is 5.5" inches wide. So far it has worked for me...but I too agree that I don't see why cardboard is necessary.

Shirlin: What a great idea, definitly under the "Why didn't I think of that" category. Thanks for the tip!

I like mine to stand up without having to stuff fabric on both sides of it. It's a lot easier to get in and out that way. Different strokes.

I"m fortunate to have a sewing room with 2 large closets. I store my yardage in those over hangers and the smaller cuts in plastic boxes on shelves. I've never done the 6" ruler fold. I guess I still have a lot to learn!

Personally, I ruler fold my fabric with a 4" ruler, it works for me and the space they need to go in.

I use the 4" ruler for smaller pieces and 6" ruler for larger pieces. I have to lay them flat and this works with the space I have.

I too have a lot of fabric but I have them bundled with the projects they will end up with in stacking drawers. I have way too many filled in this manner. I can't afford to just go and buy yardage without a purpose for them.

From OP - some of you are just quicker than I am! LOL It took me a while to realize that any ruler would work, so I thought I'd share. I've been sewing for 60 years and I'm still learning. Sometimes the electricity flows but it takes a while for the light to turn on!

Hi to all. I'm a newbe. I don't understand folding on a ruler. Can someone explain?

Welcome Happystitcher. Ruler folding is generally done with yardage, not fat quarters. When you buy fabric yardage it is folded in half lengthwise with selvedges together. Fold it lengthwise again by bringing the center (folded) edge to the selvedges. Now lay your ruler across the end of the fabric and begin rolling the ruler with the fabric on it. Remove the ruler and store your fabric in the way that is best for you. I used to put mine on edge in dresser drawers. Now I stand them on shelves. Some use plastic bins. The point is that you can see the edges of your fabric so you know what you have, and you just unroll the amount that you need (like in the fabric shop) when you are ready to use it.
