The only tools you will need for this box are a sharp pair of scissors and a hot glue gun.
Hot glue guns are available at any craft store. If you think you may have use for a glue gun in the future then pick a nice one but if you are just going to use it for the favors buy the least expensive one you can find.
The glue comes in a few different formulations but any hot glue should do. If you are in doubt ask at the craft store and they should be able to help you.
This is a straight forward design and only requires that you be able to wrap the box in ribbon and tie an knot. Of course you could substitute any other dried or artificial flower.
The ribbon should not be to wide as to distract from the size of the flower.
As in tying any knot, an extra finger can make things go smoothly, so get a helper.
Gather all your tools and materials on a clean and well lighted work space.
