I have one and I like it very much! It is fun and easy to use and provides beautiful results. There are so many designs on the cards which provides so many possibilities. I will also use this for spacing brads and other small items. The holes are nice and big. Overall, this was a good find.
Used in this layout: Sweet Baby Girl
I also have the flowers and flourishes template which I have used and love. Its so simple to use and looks great with stickles! I just line up the stencil, make small pencil dots in the holes, then add stickles dots over the pencil marks. Much cheaper than buying individual jewel designs.
Used in this layout: Hera and her Hamster
I just finished a project on which I used this template multiple times. They are so easy to use and are great for lining up anything little from gems to eyelets. Even Stickles dots!

I have not yet used then on a card but have been playing around to see what it is like to use.
They are very easy to use, and improve my border looks (straight when I want them straight)
