Do you have any special rulers you use a lot?
I use almost exclusively Omnigrim rulers because they all measure the same. I do have a deston plate wegde that I use to make sunflower blocks.
Love Omnigrid and use my 6 x 18 and 6 1/2 square almost daily. I also like my June Taylor Shape Cut for strips. I have gone through 2 of them so far. I like to replace them from time to time because I feel the grooves wear and affect the accuracy of the cuts.
I recently started using the Omnigrip (the green ones) and I love them! I use the 8.5 square and the 8.5 x 24 all the time. I am slowly replacing all of my old rulers because they have lost their corners.
I can pretty much do everything I need to with the Easy Rule 6 1/2" X 13" and Easy Rule Jr 3 1/2" X 9 1/2" by Sharon Hultgren. Easy to read numbers and easier on my eyes. I have other rulers and squares, but these are my daily rulers of choice.
I have 4 that I use almost daily. Omnigrid:8"x14" (Fons & Porter), 6", 4 1/2". Quilters rule: 6 1/5", I use this one to sq. 6" blocks. If I were to choose just one it would have to be my 8"X14". Love that ruler--have 2 because I have a sm. crack in the corner of the first one and would be lost without.lol
I use my 4X15 ruler constantly for rotary cutting. Like Beverly I love the June Taylor Shape Cut. It does seem easy to nick, I wish it lasted longer before it's time to replace it.
