Soak oasis and press into a standard dish with your palm
Bevel edges (so there is more space to fill with flowers
Put anchor tape diagonally across the oasis
Add a piece of leather leaf in the center and each side of the oasis
Fill in all the space with leather leaf ( no further than the highest and widest points
Add a flower at the center of your arrangement, no higher than your leather leaf. Add five other flowers around the bottom of the oasis as well.
Fill in most of the empty spaces with another type of flower.
Keep adding until your arrangement looks full
Add your "filler flowers" (in this case I used solidago) into all the little empty spaces and you are done!
