Considering diy door panels?

For you guys who are making (or have made) your own panels: How are you attaching them to the doors? Since the original clips are sandwiched between two layers of board, I'm trying to decide how best to deal with mounting. Thx!

Just like RRR said - trim/sheet metal screws work great. Here are a few ideas.
