i used card positioning systems' sketch number 161. it's a dandy, imo, and the rounded rectangle shapes just sorta said "outer space" to me...hence the monsta theme!
i only realized just now, as i went to grab the link, that i inadvertently flipped it during printing. which is why my card is the other way round...but none the worse for it, i don't think:
(monstas cut from paperchase giftwrap; patterned paper: dcwv, love elsie; glossy black cardstock: ranger; plain white paper: staples; vintage: game pieces (they were square tokens with stars on, i cut the stars out); rub-on: carolee's creations; adhesives: tombow monorunner, 3m foam tape)
i wish i had preserved the proportions of the sketch a bit better, though. specifically the black and silver star panel is a little too wide in my version, and it makes the card feel slightly crowded. this is what you get for cutting the card base FIRST and being too lazy to get up and get another piece of cardstock. ah well, worse things happen at sea...and in space...yet alien monstas still seem pretty cheerful, don't they? what a good example they set! :)
