Tappits are strips of cutter shapes that are fairly small & shallow. They're tricky to use, but you can get pretty intricate shapes with them.
You have to roll your fondant, gum paste, 50/50, or mexican paste very, very, very thin. I like to dust the counter, the paste, and the cutter with corn starch--not much in the cutter or it will ruin the shape.
If you use fondant mix in a little tylose. Press your cutter into the paste firmly and move it around on your countertop while pressing on it. Flip the cutter over and use a small rolling pin and run it over the cut shape to get a nice even cut. Or you can use your finger to go around the edge. Flip it back over once again and "tap" it on the counter--you may have to tap it harder than you'd think. The shape should pop right out, but if it doesn't, use a pin to get it started and tap it again.
The key is to rolling that paste very thin.
Thank you very much! Im going to order them and try it out. I love the fonts.
