My bouquet is made of sola flowers with a huge cascade. I'd love to have it laying flat on our sweetheart table with the cascade flowing over the edge of the table for our centerpiece. However, I cannot figure out how to secure it so it won't be falling off the table or moving somehow. I can't use a vase since it'll be horizontal. The weight of it may be around 3 lbs with the greenery and a couple succulents. Does anyone have an idea of how to go about this?
