My success in this project is due to the excellent instruction provided by UK crafter, Caroline Hallett "CraftyHallett." Search her on YouTube; she's got a lot of great videos. Her measurements for the Christmas crackers which I made worked out perfectly. If you've got a particular gift you're looking to "wrap" in a cracker, Traci Cornelius (another UK crafter) offers a great video on figuring your measurements. There's such a wealth of information out there!
The Stampin' Up! Envelope Punch Board (#133774) can be used to make so many fun projects!
