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!

What was that on? I have never in my life seen that. Mine had rectangular holes around the perimeter of the panel on three sides, with the spring clips slid into the holes and just slid over the board. Then the original panel cover right over them. That's the only way I've ever seen it. I actually did that to mine and installed the clips, but they were bein a double barrel bastard, so I removed them all and used self drilling screws. Just like these.
