A nice easy step for this stage, take your wrapping paper/coloured paper and glue your template to it. Obviously you want the coloured sideof the wrapping paper and the printed side of the template side to show.
Make sure that the Wrapping/Coloured paper is of a larger size, so you can trim it down after you've glued it. This means no white patches near the edges of the cracker.
I used standard "Pritt Stick" type glue, however you can use what you've got handy, as long as you can get a nice evenly stuck bit of paper.
Trim the excess Wrapping/Coloured paper off using scissors or scalpel.
