How to make a round mound

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!
