hello Does anyone know how to make a spider mum?? Thanks to all.

Do you mean a gum paste one? If so, it is very detailed and takes a lot of work. Essentially, you take fairly thin floral wire and work a ball of paste onto the wire and down a bit leaving a small ball at the end. Insert tool in end of wire where ball of gum paste remains and create a small opening. slightly bend wire and hang to dry. You do this a gazillion times with varying amounts of paste on the wire so that you make different length rows of petals to go around. For the middle, you take a sturdy piece of florist wire or wrap several together, hook it, then put on a ball of paste about the size of a grape. Let it dry. Then when dry add a very small thin daisy cutter flower (with petals long enough to go up and over the ball of paste that you put on the wire and make sure to use the ball tool to smooth the cut edges on each flower) threaded through the paste, attach with gum glue and wrap the ball. Add another, and overlap and offset the first leaving a little more of the petals unglued. Continue adding and increasing the size of the petal cutter as you add layers. Once you have enough layers to create the tightly clasped petals in the middle let it dry over night. To assemble, take the tight center and then slowly wrap the smallest petals on first, one after another and then layer down and add the next size, then the next and so on until you have finally added all of the petals and then continue down and wrap the stem.

Like I said, it is very time consuming! You could easily have 100 petals for one flower.

You can make smaller regular mums out of butter cream if you add enough meringue powder so it crusts very stiffly. HTH
