I use Satin Ice readymade fondant, roll it out not too thin, then let it sit for a few minutes so that the side that will go into the letter cutter is somewhat dried. If it the letter doesn't snap right out of the cutter, I gently/carefully use a toothpick or the pick from my fondant tools set and work it out. Sometimes you have to reshape it a little. Then I let all the letters harden before putting on the cake.
