Making your Own Pot lids.

I want to make a couple lids for my Optimus pot set, just wondering what methods you guys and gals have come up with that work well, I know the easy tin foil method, but looking for something a little more professional. I only want to make the lids so I can use both pots at the same time.
I was thinking of using Milo Chocolate drink lids, from memory those are very very light, I was thinking of using some normal can lids off normal stainless steel cans, but they seem to be pretty heavy. The Milo Tin lid will only work if they fit, so I guess I better go see if they do which every size of tin is closest I will try.
Thanks for any suggestions.
Cheers.
