These cookies add dimension by using mini Christmas cutters.
(I own more than my share.....and it was fun to finally use a few.)

Plan ahead by finding the best background cookie to accommodate the mini-Christmas shape you've picked out. As you can see, the star needed a longer base, so I chose the long oval. Each mini-shape has it's unique needs for the surrounding base cookie.

The cutting out of the mini-Christmas shape can be as simple as just impressing the cutter into the base cookie before baking. But you can also add more dimension by cutting a very thin dough version of the mini-shape and place it on top of the cookie.
(see photo below)

Once the cookie is baked and cooled, start decorating the shape in the middle. There are so many possibilities on how to make it stand out and give it "bling". For the cookie below, I first flooded the cookie with white glaze and then sprinkled edible glitter white squares on top. (Warning: they tend to wander all over the house!)
But as you can see, there is a plethora of sprinkles and dusts you can utilize to add that special touch.

After this Christmas tree was flooded with white glaze, it was covered in Silver Pearlized Sugar Crystals. 

Once the middle shape is complete, outline and flood the background cookie.

If desired, you can also choose to make the background have all the bling/shine, and leave the middle shape plain.

To add some sparkle to a dried decorated cookie,
you can paint with a silver dust mixed with vodka or almond extract.

These cookies are simple, yet elegant and pretty at the same time.
