I have 1/24 decals that I would like to reduce to 1/32, the question is what is the percentage that I have to use to do this? The scale qualc says 75% but I think 50% would make it 1/48 which is smaller than 1/32 Am I missing something? I have been known to do that,just ask my wife! Of course she doesn't know the answer either. Any help appreciated.
