these two are an interesting pair. top one from finn is made out of some slick paper and the bottom one is a wild combination of paint splotches with matt stuff, shiny stuff, glittery stuff, markers, and more. it looks like it was a whole lotta fun to make. the stmap colors are very similar. even though the style of the stamp isn't anywhere near the style of the envelope, they still look nice together because of the common colors..
same goes for finn's choice of a black stamp and lettering on the kitty cat. even though these two envelopes do not share a lot of the same color, i really like them together.
