I have been hearing from some of my girls, that they have been having issues with their embossing folders.
I believe it is because no Big Shot is calibrated the same....some are tighter, some are looser. I have two Big Shots and they are different as day and night. I personally have not ran into issues with tearing or bending, but I know that lots of other people have.
First off, I ALWAYS recommend that you run the open end of the folder through the Big Shot First- it puts less stress on the fold, and hence less stress on the cardstock.
So, that being said, I have come up with two solutions for you.
I believe that the problems occur mainly with the Whisper White and the Very Vanilla cardstock. This is due to the fact that these cardstocks are thinner than the rest.
The first solution, I have heard about, but not tried myself, is to lightly spritz your cardstock with water prior to running it through the folder. The downfall with this one is you have to let it dry a few minutes/
The second solution is to take a piece of vellum and permanently attach it to the inside of the embossing folder that is giving you grief. I have not tried, but have seen a video from another demonstrator. This works!
Hope these tips help you out. Let me know. And if you have any tips to share, please email them to me so I can pass them on to others!
