I've made a bunch of Curvy Keepsake boxes, and every time I thought I had an original idea I would find it already done on Pinterest. Basicly they are simple Punch Art. Here is one of the ones for Halloween. Frankie!
Paper: Wisteria Wonder, Basic Black and Whisper White CS
Misc: Curvy Keepsake Box Framelit, 2 1/2" Circle, Owl Builder and 1/2 Circle Punches, Hearts Collection Framelit.
