Hopefully this is in the right spot. If not I know that the eagle eyes will catch it and put it where it belongs...

Does a Square pan need the core in the center like the round does? I'm thinking it doesn't but I am willing to be proven wrong.. ~

I recommend it and use one for anything over 10". IMHO

Ok. I know the center is the last part to bake of course but I didn't know if round pans had something special going on..lol I just bought a three tier square pan set and it said nothing about a core but my round set did.

Thank you

You can use flower nails, to save having to buy cores

I have a core just wasn't sure if I needed to use it.. I also have the nails! ~

I use a core or flower nail for 12in and up. I usually just use the nail for like 12, 14. and start with the core at 16. the core is a pain as far as i'm concerned

I use a nail for 10 in and up. 12 inch get 2 and a 14 gets 3. I may be overdoing it, but I would rather have an evenly baked cake with a few little holes than one that is dry and crusty on the edges and not quite done in the middle. IMO

I use 3 flower nails in the form of a triangle . It below a lot. I do recommend using them or a core.
