MariaK38: I put the fondant out as soon as they came out of the oven. But since I made the fondant ahead of time, I also used a vanilla syrup to help them adhere, just in case.
Also, the size of the cookie cutters were: 1 1/2", 2" and 2 1/2"
I bought the 11 piece Ateco set - it's great, in case you need to change sizes.
Apti: The dobord was wonderful! I used to used wood strips when I did a few cookies, but doing this many it was the best! No worry about the strips moving, the cookies came right off the board if I didn't use parchment - it was worth every penny.
I didn't use it for the fondant, though. It came a little too thick for my liking because it was a small cookie.
To me, I think the 1/4 and 3/8 made a difference. Not sure if anyone else would have known, but to me it did.
I'm happy to answer any other questions. THanks again.
