I am so excited about this easy, recycled decoration! We took old milk jugs, and cut triangles, a circle and some trapezoidal shapes. Then I tried attaching them by magnet to the door...until I realized that just because this door is metal does not mean it is magnetic! :) So we went the easy route of masking tape. I am not sure how long the tape will keep them on there, but it was easy enough to tape them back up anytime! Such a fun and easy (and FREE!) Halloween welcome!
