For a sturdy, inconspicuous, and easy way to secure foam to containers such as vases and bowls, use OASIS™ Anchor Pins. Simply glue the back of the pin to the container; when dry, gently press your soaked foam against it, until the pin is completely inside of the foam; the foam will now be secured to the container and ready for you to arrange easily and without conspicuous foam or pins. The pins are subtle, but strong enough to hold any foam and arrangement in place perfectly for your event.
