In regard to using Sizzix dies in the bug, I have found that the larger Sizzix originals (the thicker ones with the red base) work really well. I also have some smaller ones that are the same thickness as the bug dies and the only ones I have had a problem with are the word ones, "happy birthday" etc. They don't cut through cleanly and I have to spend time separating them. I have tried various sandwiches and will keep on trying till I come up with something! LOL.
