We did a triple feature movie night - made an 8x11 cardstock invite and added a little admit one - that I printed from an image off the net and just cute along the lines to make it 3D.
Yep - you guessed it - our walmart cake - they custom did it to her colors and added as many ghosts as we wanted.
If you blow up the picture you can see a couple things... I learned to invest in things that I could keep using (yes I still have those plates :) I did chocolate chip cookies and dipped them in chocolate, a few sprinkles, marshmallow mini eyes and a little frosting for the month. Our goodie bags were Frankenstein shaped bags filled with movie candy - spree, m&m's and more!
