Hi!
I am making a Thomas the train cake - and purchased the Wilton Choo Choo pan. I've read to tie the two cake pans together - but I don't know what string to use that is oven safe? TIA

When I roast a chicken, I truss it with kitchen twine. I've never had a problem with it burning, so I don't see why it wouldn't work for your purposes.
There are also oven safe rubber bands that can be purchases as well. They are in a variety of sizes. As previous poster - I use them on whole chickens and place in my vertical rotisserie at 400 degrees and they work perfectly. You should be able to find both the bands and string at Bed Bath and Beyond.
Buy an all cotton string and you will be fine. You just don't want to use a plastic or nylon mixture.
Most of the 3D pans have clips that come with them to hold the pan tightly together. If there is room for them on this pan, I'd get some. Here are some on ebay, to show you what I mean: http://cgi.ebay.com/Wilton-3D-Universal-Pan-Clips-pkg-8-/250539178898?pt=LH_DefaultDomain_0&hash=item3a554c7b92

The train doesn't have the ledges. It needs the string to tie it closed.
