Meltdown! (A metalic crayola kind)

Another beauty I've done from Pinterest.  My sister-in-law actually gave a couple of these for Christmas and we just did the first set.  We hot glued the crayons to the canvas (I read this wouldn't work because it would melt...but it didn't cause me any problems).  We had taped a heart in the middle with painter's tape but because of how we arranged the crayons, it didn't turn out like I'd like.  I decided to melt some more to cover that white area and here is the final outcome.  I used an embossing heat gun.
