This is how I do my deco-den for a compact mirror.
Step two: Decide how I want my mirror to look like, determine the theme and the main colour. In this case, I am choosing desserts and pink respectively as the mirror is for a friend of mine who is giving it to his sister as a birthday present:] Put the large cabochons first. I purchased mine from Sophie and toffee and Daiso.
Step three: Next, put the large gems. I wanted a border for my mirror, so I taped the sides to ensure that I do not dirty the sides with glue. *I started on the corner before I remembered to take a picture;] Tip: Use more big gems to make your mirror more striking (and save a lot of eye power to put in tiny gems)
Step four: Starting from the border, apply glue with toothpick, put on the rhinestones with a tweezers. I use those with a curved tip, but I guess you can use whatever suits you:] Tip: Apply a little glue on a small area at a time. This prevents the glue from getting dry before you actually get to the area. As you can see, I was slowly inching to the centre.
