The Wilton cutters and book set are order # 1907-P-1003 and is $7.99 plus shipping and all that stuff.
basically...you take a toothpick (I use the more *upscale* thicker ones instead of the cheapy wooden ones - know what I mean?) Then take a toothpick and dip it in crisco (just the tip) and then take a small amount of your fondant and roll it into a teardrop shape and then push the toothpick through the bottom of the teardrop (the big end). I like to let these dry before I do the petals - it's just easier. So...get yourself some styrofoam to put a whole lot of toothpicks with flowers on them in.
Thin roll out your fondant REAL thin - it's best to add a bit of gumtex to it for pliablity (is that a word?). Then use the largest cutter to cut the fondant place a small cut where the petals *divide* then you place it on the foam that you get and give the edge of the petals a little rub and the center with the ball tool. Then you paint some vanilla on the bud and fold the petals fold it up around the *bud* that you made. This makes a rose bud! All petals will be attached from the bottom of the toothpick and then slid up.
To made a medium size rose you add another blossom shape but, you will press it differently with the ball tool and then paint the last *blossom* you did with vanilla and stick the next one on.
To make a full size rose you add another blossom. So...it's all basically the same just each layer gets pressed a different direction to make it fan out like a rose. On p. 21 of the Course 3 book it has pictures and explains it. But..if you are buying the cutter set then no reason to have both books.
Then you add your calyx/sepal in green and let it dry.
The hardest part is getting the fondant thin enough to make it look real nice. If it's too thick...it looks nice but...not as nice as the really thin ones.
Does that help any? It really is easy with the right tools.
