First thing to do is divide and tint the frosting... tint about 1 and 1/2 cups green, the take half the rest and tint it yellow, and tint the other half orange. Place half the yellow and half the orange in one of the ziplock bags 1 color on each side, put the rest in the other baggy the same way(later you will cut the corner of the bag to make the petals)
Next step is to frost a smooth layer of green onto your cupcakes
Then take your oreos, big and small, and place them randonly on your cupcakes and press so they stay in place.
next take one of the ziplock bags, rienforce the corner with the tape then cut a petal shape, start piping around the cookie where the frosting in the middle is then go around again on the top. Do this by squeezing the bag and at the same tme pulling out to form the petal, remember practice makes perfect.:o)
to make the green leaves, use the star burst or airheads, first roll them out on the sugar, and once they are thin enough(anout 1/8 inch) cut them into leaf shapes, place them on the cupcakes by the flowers.
