I used Early Espresso cardstock, the Jolly Holiday DSP and the Sparkly & Bright Stamp Set.
Inside the Treat Bags I added a sheet of christmassy owls (sorry the photo looks fuzzy, but it is just the reflection from the cellophane bag). These owls are on dimensionals which are then stuck using double sided to the background cardstock, they can then be removed and stuck onto any project they like.
I also added a little bag of chocolates (a treat bag has to have some choccie treats), the mini post it note holder and a little container of Stampin' Up! goodies (brads, buttons, etc).
