I bought some beautiful fall silk flowers and I put them in a vase and I just can't get them to look right. Ideally, the tallest flowers should be two to three times as tall as the vase you're using. That will depend on the size of the vase. The larger the vase, the taller the flowers should stand. Otherwise, you're going to draw attention to the vase rather than the flowers.

Arranging silk flowers is much like arranging fresh ones. You should start with some short greenery around the top of the vase to hold taller flowers in place as you add them. That way you get an idea of where you think the taller flowers would look best in the vase. When you start from the bottom and work your way up, the idea of how you want the flowers and the vase to look will be there before you know it.

I'm not sure which look you're going for - loose and airy, or rich and dense. If you're going for loose and airy, it's best to use flowers in odds. I start around the base of the vase, using an odd amount of the same flower in even spaces. Then the next layer toward the middle will be a bit taller, and the same flowers will fall sort of in between the first layer.

Reduce the number of flowers you use in each layer until the arrangement is pleasingly rounded on top. Then fill in with accent flowers. With this type of fall arrangement, I always recommend to use some wheat, cat-o-nine tails, or some curly willow tips which are my personal favorite, to trail off from the top of the arrangement.

If you're looking for rich and dense, then I recommend grouping in similar colors and textures. When colors are grouped, it has a much larger visual impact than if they are peppered throughout the arrangement. So grouping is perfect for making a bold statement. I'd also use larger flowers for this, such as clusters of hydrangea, sunflowers, large mums, and roses. With this type of arrangement, you'll stay away from too many fillers. They'll just cause a messy appearance.

When I'm using large flowers like these, I make a basic circle around the bottom, beginning the color-grouping, then I put a tall flower in the middle. Then fill in between with groupings of flowers. Depending on your personal preference, you can make the groups very defined, or you can sort of fade from one color group to the next by mixing a couple of flowers with the neighboring color.

Whichever type of arrangement you choose, try to use various heights and depths. The general idea is that the center flowers should be the tallest, the outermost flowers should be the shortest. This is a good rule to make the basic frame of your arrangement by. However, if you follow this to the T, you're going to end up with a blah arrangement that isn't very interesting to the eye.

So once you have your foundation flowers in place, make sure to stick a few flowers a little deeper than the ones surrounding it, and a few just slightly raised from the rest. This will keep the viewer's eye moving and really draw them into the arrangement.

They will be able to see all the colors of the flowers that you put in the vase and be able to admire the way that you put them together. Just make sure that when you put the flowers into the vase that not all of the flowers that have the same color are next to each other. Use different kinds of colors next to one another. That way, you will be able to see certain colors bring out other colors.

With most people, when they do flower arrangements they sometimes use the same color next to each other and that makes the people that are looking at your arrangement think that the flowers are too big to be put in the vase. So try to avoid that kind of thing. You can use the same color next to each other as long as one of the colors are either darker and lighter than the other one so it won't throw off the look of your arrangement.
