I have a dinner party next week, and I wanted to have a comfort and classy feel. I consider using a tall arrangement where I would use a Gladiolus flower as the center. I discovered some beautiful glassware and minimalist planters on abodelook which I believe will look quite contrasting with the bright colors of the petals. Does one have suggestions about how to keep them in an upright position in a thinner container or do I just keep using the tall floor vases they have on its site?
