I've got a card for the current CASE Study Challenge.
This was the gorgeous inspiration card:
I was inspired by the pattern on the inspiration card, but had no stamps like that, so I decided to make my own pattern of sorts. So I inked up a stamp from Papertrey Ink's Delightful Doilies set, stamped it multiple times to make the pattern, and then added a sentiment on white cardstock matted with black cardstock.
Cardstock: (white) Recolletions/Michaels, (black) The Paper Studio
Clear Stamps: (doily from Delightful Doilies set, sentiment from Think Big Favorites #6 set) Papertrey Ink
Dye Ink: (Bahama Blue, Tuxedo Black) Tsukineko
