These special rulers have been on my wish list for quite some time. The idea is wonderful and I had hoped my frequently lopsided layers would stop. I am having some difficulty with the rulers moving even a little. Hopefully, with practice this will stop.
I purchased a set of two of these years ago...like 10 years ago maybe...they are perfect for getting straight and even borders around photos or anything that is being layered. Aside from my paper cutter/trimmer, these rulers have been the most used tools in my giant scrapbook tool collection. I love these! Now I see there is a third ruler...these and an exacto knife...the even-est layers ever.
