Now in general use, plastic-holders are generally types of foamed urea. They are water-retentive and yielding. So long as are not too soft and sappy they will enter the plastic easily and be held firmly. Only a short portion of the need be inserted for it to be anchored, which means that quite short-stemmed can be used in a number of attractive ways. Often they can be made to appear long-stemmed.
Obviously stem-holders should not be conspicuous. Wire netting inside ais well masked but a pin-holder or a block of plastic might easily show. Fortunately, the means we use to hide these holders also add to the interest of the flower arrangement itself and can even be an important part of it. Sometimes it may be necessary to do no more than arrange the largest flower in the group so low that it hides all trace of the holder from which it leans. Often, and this is a pretty method, a group of large can be arranged like a little skirt around the base of taller . One can also use a mossy stone or two, a group of shells, some driftwood, fruits, a whole plant or any natural material which seems to have an affinity with the particular flowers or materials being used.
