These folders are great -- they are a deeper emboss than some of my others, so they really stand out! So far, I've used it on cardstock, thin cardboard/chipboard, and plastic, and it's come out perfect! I can see what the Tim Holtz fuss is all about now :)
I love his products. This is a new one and it works well. I am a big fan of anything he makes as he puts a lot of thought into his products.
