This Oasis heart is made with SuperMax foam, perfect for any fresh flower design. This foam has proven to keep flowers fresh longer than plain water!
Note the generous depth of the foam, allowing you to insert flowers from the sides so that no mechanics (the plastic tray) will be seen after the design is finished.
Soaked foam is actually quite heavy because of the absorbed water. If you wanted to use this for a flower girl to carry, I would suggest you use the smallest mini heart that measures 5" across rather than the larger heart like this 9 inch one.
Because of the weight (especially once fresh flowers are added), make sure that the heart is securely fastened in place. Definitely use wire or zip ties - do not use lightweight ribbon.
Placement is really up to you. It doesn't have to be perfectly centered or identical mirror images. I'm going to stagger the look, placing one heart up a little higher than the second heart.
