I have thoroughly searched the Loc Bloc ruler sight to see what all they offer. They have an item listed as Strip Ruler I believe but no photo just a size of I think 7 inches by 10 inches. I sent an email asking if there are any images of this product of if they can explain it but they didn't respond. I am having the wobble effect as well on some strip sets I am trimming (3 strips sewn together). I don't like it when the ruler is "sticky" because then it is too hard to move it around to position it just right so I don't like the dots or sandpaper holes.
