The measurements for the card in the Pop-Up Box Card tutorial are for a card that fits nicely into a 6"x9" envelope (the finished size is (5.5"x6"). This card is done using measurements and instructions I added below the tutorial for a finished size of 4.25"x5". This is the vertical version. Stamps are from The Cat's Pajamas, and the images are colored with Touch Twin Markers.
This is adorable!!! If I can squeeze in any time, I want to create one of these fun boxes. (I kind of thought we would see a ton of them for our theme!) Great texture on your stars!
