Black posterboard (I bought 3 sheets from the dollar store at 69c each)
Exacto knife and a self healing cutting mat (or you could use cardboard) to protect your work surface
Yellow tissue paper
Tape and glue
Cut your posterboard into strips that will fit in your window and cover them completely...but don't tape them in yet.
Lay the strips out on a cutting mat or piece of cardboard and cut out some spooky eye shapes with the exacto knife. You can find some images online for reference, or even print some out to trace exactly. But you don't need perfection here.
Cover each cut opening with your colored tissue paper, securing with tape. Cut small circles and ovals to glue onto the tissue paper as pupils in the eyes.
Put the posterboard up into your window and tape in place.
Here's what the front door looks like during the day.
