Use the Bellissimo Flexi Smoothers on freshly-covered cakes while the sugarpaste is still soft. For a round cake, hold the smoother with the curved edge on the top of the cake and hold the straight smoother against the side of the cake. Apply light pressure and gently run the two smoothers together around the top edge of the cake. You will notice a crisp edge starting to appear.  Watch this video for full use.
