Depending on the vase and type of arrangement Learner wishes to create (see class description above), Learner may need either a simple vase with flowers and leaves, or a Japanese vase or "suiban" (open and low) with a pin frog (kenzan) where they may want to include wood, rocks, moss, twigs, or even fruit!  If this arrangement type is chosen, please make sure to have the vase and a kenzan, plus any other element Learner would like to include.  

You may also want to have handy the following:
sheet or paper where to rest the branches and stems while working (it will protect your table surface and be easy to pick up the little pieces of stems, leaves, etc.  afterwards)
bowl of water where you will cut the flowers and branches under water 
scissors
a hand towel
flowers, branches, leaves, etc.
water canister
