Sorry to make everyone so crazy! I know that I didn't explain it very well at all so I will try again!
First of all, I DID contact Sizzix as soon as I saw the problem and yes, they did consider the die to be defective and sent me a new die right away! Customer service was wonderful this time. The new one works perfectly so I'm so glad that I questioned the first one I had.
Ok......as far as the not cutting through the cardstock. Yes, I could have used a shim to try to make it cut better through the cardstock but it was a 3 inch section in the middle of one of the 5 inch sides that was the problem. As my other 4 Flip Its cut the basic shape perfectly, I really didn't feel like I always wanted to have to try to shim that section in exactly the right spot each time if I didn't have to. However, if the cutting was the only problem, I probably would have just done whatever I needed to do to make it work.
Now, for the "backwards" part that I explained so poorly before. The cut out die shape has a "right" side and a "wrong" side, much like a piece of fabric, if that helps. It wasn't that the shape was backwards per se but rather that no matter what you did, the "wrong" side of the die always ended up being the front of the card - the nice , clean cut was on the back of the card. Even if you covered the cardstock with printed paper cut from the die, the front of the card would not have that nice, finished look. Does that help explain it at all? It always looked like the back of the card and there was no way to fold it to look right.
Just like when you cut your cardstock on a paper cutter, the cut looks cleaner on one side than the other? At any rate, my other 4 Flip Its, when folded, have the nice side facing front AND, now, with the replacement heart die that just came, the nice, finished side faces front as well. So, there was definitely something wrong with with the first one I had. It really had me confounded
when I used the first one because I just couldn't figure out what was wrong, what I had done differently because there really was only one way to put it through the Big Shot. I'd done 50 plus of the Square Flip Its for my Christmas cards so it wasn't like I hadn't used them before. To have the "finished" side be the front of the card, the card either had to be upside down with the point of the heart at the top or the wider side of the card had to be on the left side with the narrow side of the card on the right (opposite of how it is supposed to be). Trust me, I turned and folded the card every which way to try to make it right.
So, I guess the most important thing here is to say......if you have any of the Sizzix Flip Its dies, be sure to check them out, even if you don't plan on using them soon. There seem to have been some manufacturing blips along the way. If you purchased directly from Sizzix, they will send a replacement right away BUT you need to go back to the retailer (online or brick and mortar store) to resolve any issues if you did not buy directly from Sizzix. I did not realize this at first.
Sorry for the long post! Just know I had confused people with my earlier post. Hope this helped to explain it better!
P.S. Jeanne, love your card posted above - and yes, it is exactly right!
