Yes, I have a bunch, they also give you inspiration for other items you might have in your stash.
Get the photo templates. I kept passing on them and I finally bought both sets. I am so glad I did. The photo templates have the measurement on them. Being cutting challenged, I used my gypsy/cricut plugged in the photo template dimensions, make sure you keep it on "Real Dial size" put your paper in and it cuts your mats while you work on other parts of your layout. Love it!
I also started to feel more comfortable mixing stronger patterns, using up older stash and just being able to be more creative.
Here a couple of layouts I did with the border templates and wacky set:
This reminds me I need to upload some of my completed layouts. I don't think you can go wrong with a purchase from them.
