I created this set of cards for the May '09 SheetLoad of Cards. The sketch this month features a square card and a scrapling.
I made the butterflies on the front of each card 3-D by stamping a second copy on patterned paper and only adhering the body to the card - this allowed for the wings to be folded up.
The base for these cards is a SheetLoad ShortCuts Clear Card Blank.
