First I LOVE the Monster Bash papers. Second this is a great layout regardless of the papers you want to use. This is a layout shared by a member of my demo team. Each month she posts a sketch for us to follow as a card challenge on our Scrappin Demo Facebook page. This is a great way to use up those smaller pieces of paper.
Card Base: Cut Basic Black 8 ½ X 11 paper in half width wise. You now have two pieces 8 ½ X 5 ½ . Fold one of the pieces in half lengthwise for your card front. The card front now measures 4 ¼ X 5 ½.
Card Mat: Cut Pumpkin Pie paper 4 X 5 1/4
Cut 3 pieces of Monster Bash paper 1 1/2 X 3 5/8
Cut 3 pieces of Basic Black 1 5/8 X 3 3/4
Attach each piece of Monster Bash paper to Basic Black mat.
Attach these 3 pieces to Pumpkin Pie Card Mat. Attach card mat to card base.
Stamp sentiment with Pumpkin Pie ink on Whisper White paper. Cut out with stitched rectangle die. Cut mat with next size rectangle from basic black paper.
