Just be a little careful if you are using a regular carpenters chalk line as when you "snap it" the chalk tends to fly every where......and am not sure how 'washable' that chalk is for construction use......I would sure test first.....

My husband has three of those in the basement. Maybe one will find a new home in my sewing room.

Just be careful you have a large enough surface when you use it. The quilt can slip and slide underneath the T-square. You want to position the quilt corner as flat as possible before placing the T-square on top of it.

I will try a test before using Carpenter's white chalk on a quilt. I think if you carefully snap it that the chalk shouldn't fly further than what the binding will cover. I will post after I try it and tell everyone how it works but that won't be until September. I have my top ready but I still have to machine quilt it.

I should mention that it's also possible to use laser level squares from the hardware store to square up a quilt. Here is a tutorial on using them to block a quilt, but they could also be used to mark a quilt for cutting:

It looks like a really neat method, and more accurate that just working on individual corners, but I don't have the space to try it out.

Thank you for asking this question. I was just sitting here at my desk wondering the same thing and thinking about posting on the board. You saved me from having to ask.

DH has many laser levels. He keeps getting them for Christmas from various relatives. LOL. I think I'll go get one and try it out.

I use my square floor tiles as a guide. I guess they must be straight and squared enough.

I should add that when I use the metal T-square, I don't like to use my rotary cutter. Instead, I mark the cutting lines using the T-square, then switch to my large plastic ruler and rotary cutter to actually cut on the lines. It's too easy to nick your rotary cutter blade on the metal.
