4 1/2, 6 1/2, 9 1/2. Wish I had a 12 1/2.

20-1/2 is my largest. I don't use it often but am so glad to have it when I need it. I use the 12-1/2 the most. Also lots of use for the 6" and the 6-1/2". I had a 3x18 ruler that broke in half and I loved the 3x9 size til I wore it out. I use the 6x24 lots too.

I have a 20" (from Jo-Anns), but I could'nt live without my 12 1/2"

Thanks again, everybody!

12.5

My largest is 18 - the block marker by sewing revolution.. it squares up 12 inches to 18 blocks..

I signed up for joanne's flyer she said it would come in about 3 weeks. As soon as it comes I'll be buying a 12.5

Me too and I use it all the time. It's wonderful for squaring up your blocks as well. :D

The 20-1/2"...don't use it lots, but when I need it it's great for squaring up applique blocks.

I also use it for a faux-lightbox. I tape my applique layout sheet to the ruler (so it doesn't move), put an 'under-the-counter-fluorescent-light-stick' in an empty (shock!) Sterilite container (66 qt, I think) and then the ruler over the top...background fabric on top of that so I can place my applique shapes.

It's nice to be able to move the ruler around to get the best light for where I'm working.

Does that make sense?

I don't think I've met a square ruler that I didn't like...

That makes a lot of sense, Julie. Talk about using your resources well!
