we grid awakward cube vases when there is a clean look desired. Cubes of 3-4 stems of hydrangea have popped out in delivery too many times for me to NOT get over my aversion to gridding.
I sound like a broken record, but, if you will use different sizes of electric tapes in good colors, these few stems will not pop out.
As Cathy and a couple others have said, learn to make a karbari or an armature of some type. If it is made well, they do not pop out of the vases. And, it does not take more product, in fact it usually takes less because you base has made it easier to design and it is far faster than gridding vases.
In the square vases, I made an assortment of small greens and use the smallest size electric strip to fasten them....set it in the water, then add what ever else you need to. It should be as secure as gridding and in my case, it is more secure. Practice this technique and you will find that you start leaving all that gridding behind.
OK, I give... what's a karbari?
I never used to grid - like over the past 20 years!!
But now, in the past month, at my new job, we do tons of cube vases for wedding guest tables, and cocktail tables. (3 x 3's; 4 x 4's; 5x 5's)
The boss likes the cubes to be taped, and I agree, I feel much more secure that the low arrangements won't "pop out".
Also, the arrangement has a cleaner look; fewer stems in the water; just nice lines of the major stems of flowers.
We also do the same, flowers last so much longer when they can have a fresh cut and the water changed totally.forgot the reason we don't tape anymore. My instruction card that goes out with every design states: Vased arrangements - to change or add water, grasp bouquet at the vase top and remove in one piece, recut stems, add fresh water and flower food packet, replace flowers into vase.
Can't do that with a taped grid.
I think you might be talking about rikka.It is a japanese design style, from what I understand it is a wood cylinder with a slit that holds the flowers in place...so I would imagine that putting flowers down inside bamboo would be this style...I am no expert on this style and it is new to me since I went to college 20 years ago and it was not taught then...
