I hope I have the correct DG. I have a decal sheet a friend of mine gave me. It is in I /35th scale because the company, Fingerprint Designs, does not make their decals in 1/72nd scale. I have the decal set in 1/35th scale and I would like to know, how do you make the in 1/72nd scale? Is there a way to do this without ruin the decals?
Can someone please tell me how, step by step, to go about this?

If white is not involved the quick and dirty solution can be to buy a clear decal sheet (or a white one if white is involved ) then go at Kinko's with your decal sheets (originals and the new ones) and have a photocopy of the original scaled down. I think on IPMS Stockholm there's a conversion sheet for scaling down/up originals when you have to copy something. The link is http://www.ipmsstockholm.org
