This is a technique I learned many years ago from a floral designer based in New Zealand. As it can be adapted for so many uses, I find it one of my most useful basic techniques.
You will need:
Two circular outlines of different sizes (dinner plate and saucer for example)
Elastic bands (small size)
Suitable cover for corflute/foam board to match your design
Step 1 – Mark two concentric circles on the corflute/foam board.
Step 2 – Cut out the circles.
Step 3 – Cut in half to give you two semi-circles. This gives you a variety of ways to place the structure on the table – a circle, parallel semi circles, or a long “s” shape that can be extended for the full length of a banquet table.
Step 4 – Measure for placement of vials so that they are equidistant from one another. Make sure you have one at each end of the shape (for stability).
Step 5 – Make a hole and push the vials about halfway through.
Have two elastic bands ready for each vial.
Step 6 – Place an elastic band on the top and underneath side of the corflute/foam board for each vial. This ensures the vials do not slip.
Stand your structure on a flat surface to ensure stability.
Step 7 – Cover corflute/foam board to suit your design.
Fill vials with water and it’s ready for your plant material.
