Just drunk WAY too much coffee and need to burn off some of that extra energy?
Grab the take away tray, a pair of scissors and a pen and get to it!
Bend the tray in half but don't tear it apart.
Cut one of the ends through to allow the "wings" to flap open.
You may need to pry off the glued tab on one side.
Cut this tab off at the base and keep it to make the beak.
Fold it in half and cut it into a point at one end.
Oh Yeah you lookin soooo beaky right now...
Push the end of your scissors through below the "eyes" to create a slot for the beak to be pushed into.
Draw the shape of your wing onto each side flap and cut it off.
Trim up that bottom edge for the feathery look.
It will stand up nicely as is but you can add feet too if you want...
Cut out feet shapes with a longish leg from the scrap you cut off the wing.
Cut slots for the legs to slide into and insert the leg into the slots.
Oh don't forget to give your owl some cute ears if you have enough leftover carboard.
I used sticky tape here but you could also use the cunning slot method if you don't have any.
now go forth and decorate to your hearts content.
