Dear Robin, I have a project in mind that would require perfect 1 inch squares. The cutting device that I have now cuts strips but are not always consistent in size. Can you recommend a cutting device that can be programed to cut a 12 x 12 sheet into squares? Thank you in advance, Tammy Pike

We have two suggestions for you. We use the guillotine paper trimmer from Tonic. It's more expensive than your average trimmer, but it cuts really well. Here's a link to this trimmer on the Annex:

The second is to use a 1" square punch. You won't be able to get 144 squares out of a 12" x 12" sheet, but each square will be exactly the same size. We suggest cutting 1 1/4" x 12" strips (or close to that) and then punching along that strip. Here's a link to this product on the Annex:

Hope this helps!
