This is an easy way to make a dried hydrangea wreath for the fall and once Christmas rolls along, spray it gold or silver! For years I dried the flowers and then tried to make the wreath. Two tons of fallen apart flowers, a big mess and no wreath was what I got. The secret is to make it while the flowers are pliable not dried.
Buy (or make) a grape vine wreath, the size you want. Remember the dried flowers will look very full and larger than the actual size of the wreath.
Cut the flowers from the bush and leave a nice size stem about 8-10 inches. You can always cut them down.
Take off all the leaves and start to put the flowers into the wreath by weaving them through the wreath branches. Make sure the wreath is very full because drying shrinks them a little. Hang the wreath where you want it (not just in a place to dry). It can be messy moving it. If you find that during the week you want to fill in some bare spots, just cut more flower heads and weave them in.
