This is creation of a stencil/ mask made of hot glue and a pattern background to make an intricate design. A hot glue gun is a tool that is used to heat hot glue sticks. This type of glue dries much quicker than other types of glue. That is why we use it. Here’s how it works. A solid 4” stick of glue is placed into the back of the glue gun. The glue gun contains a heating element inside that liquefies the glue stick upon contact. The liquefied glue is then released through a metal nozzle when the trigger is pulled. This metal nozzles is connected to the heating element and is extremely hot. The glue that comes out is hot as well and you need to wait one minute for it to cool.
