Using the pastry sleeve, add icing to one of the large cookies, place the medium cookie on top of that, this will serve as glue, add more icing to that cookie and place another medium cookie on top of that. You'll have a three-layered pastry at this point. Spread more icing in the space between the large and medium cookies and let sit for 5 minutes. Place the small cookie on top, more icing and another small cookie and continue decorating with icing. Finish this off with icing on the last cookie and decorate with a sugar flower, or in this case, sugar pearls.
