Give your friends and family a sneak peek at the goodies inside their gift bag with a cellophane holiday shaped window. Start with plain gift bags. Punch out the center of your bag with a large holiday-themed punch or trace a stencil or cookie cutter and then cut it out. With a clear tape runner or double sided clear tape, tape around the cut out image on the inside of the bag. Cut out a piece of cellophane large enough to cover the image and carefully slip it inside the bag and place it over the tape and cut out image. Press down to adhere. Fill the bag with homemade cookies or other treats and then fold over the top of the bag a couple times, then punch two holes with a hole punch and tie together with ribbon.
