1 piece of black cardstock 7X9 (this is the main piece). You can substitute the cardstock for some heavy weight design paper). I will also abbreviate cardstock = CS
1 piece of pumpkin CS 4 1/2" X 7"
2 pieces of pumpkin CS 3"X3 1/2"
Optional designer paper strip 1 1/2"X7"
Score the 4 1/2" X 7" pumpkin CS at 1 1/2". Attach pumpkin CS to the black CS as shown. Sorry, the 1 1/2" piece is hidden in the back of the top section of the black CS so the fold of the pumpkin CS is resting at the top of the black CS.
Here's another view after you have attached the pumpkin CS to the black CS.
Take the two 3"X3 1/2" pumpkin CS pieces and score every 1/2" inch as shown. Apply strip adhesive to the edges as shown.
Your piece should be facing this direction to apply to the main CS (black CS).
Attach one side of the accordian piece to the main CS as shown. Repeat this step for the other side.
Your project should now look like this.
Now attach the other edge of the accordian piece to the main piece like this and repeat for the other side.
Here is what your project should look like.
