The design for the packet insert is almost the same as the one I made in 2010 using digi kit, which sadly now seems to have been retired. The font I used is 2peas Typo.
All I have done is print of the design and then mat and layer it on some PaperCellar snow design card to fit my cello bags, that I found in Home Bargains for a bargain 89p for 50 bags.
In the bags I have put a packet of hot chocolate, a candy cane and a marshmallow Christmas pole. I used to make my own little packets of mini marshmallows to sprinkle on the top of the hot chocolate, but I think using pre-packed marshmallows is more hygienic, leaving the recipient to either dip or break up the marshmallow as they choose. However at the last minute I decided to add a mini gingerbread man from a pack from M & S (99p for 12), which I sealed in a small cello bag with my vacuum sealer and a couple of starlight mints, again left over from other projects …. but all with a couple of months on the sell by/use by dates
