A flower arrangement for teacher is usually small with a low base so it takes up limited room on her desk and cannot be easily tipped over. It is appropriate to give a flower arrangement accompanied by a card at the end of the school year, the first day of school or any other time to brighten the teacher's day. Give a ceramic coffee mug holding an arrangement in the school colors or one with a witty saying on it, and the teacher will have something to use after the fresh flower arrangement has faded.
Prepare the floral foam. Select a container large enough to hold the entire block of foam and fill it with water.
Set the floral foam on top of the surface of the water in the container so it slowly soaks up the water. Don't press down on the foam or try to force it into the water.
Cut the water-soaked floral foam into a solid piece that completely fits into the coffee cup. Slice off at the top so it is 1/4 inch above the top of the coffee cup opening. Stick your finger into the foam inside the rim off the coffee cup making a hole between the foam and the side of the cup so the teacher can add water to the arrangement. Fill the cup with water using the newly made hole.
Add a small amount of greenery by cutting the greenery stems and sticking the stem ends into the wet floral foam. This will give you the basic shape of the design.
Cut the small flower stems first and insert the stem end into the floral foam to fill out the design. Then, cut the stems of the larger flowers at the desired length and stick the cut ends of the larger flower stems into the foam as needed to complete the flower arrangement.
