These are a couple of kit cards I made that came with some sheets of red vellum to use. The neat thing about vellum is that you can see through it. The neat thing about colored vellum is that, well, it's colored!
I don't think I followed their directions exactly but I know these are in the ballpark. It I had to do it again I wouldn't use the variegated inkpad for that top card because the variegation got lost behind the vellum and it just looks weird.
