Then trim your short sides at an angle so that one long side becomes shorter than the other.
Place a strip of double-sided tape along one of the short sides. Roll into a cone shape. Use a hole punch to make a string hole near the top edge.
You can use a variety of ribbon, stickers, paint, etc. to them up.
Fill with a bouquet of fresh picked flowers from your garden. If you want to transport them or ensure they stay fresh longer, use a small florists tube tucked in the bottom of the cone to hold water for them.
