White daisies tend to have longer laterals, which is nice because you can cut them apart for these smaller centerpieces.
Insert the side flowers so that the heads face outward rather than upwards.
Continue to fill in all around the centerpiece.
Turn the container frequently, not forgetting to insert some flowers in laterally on the low sides.
The flowering process really only takes minutes. Don't feel limited to just daisies and carnations. There are a lot of available flowers that come in traditional (and some "not so traditional"!) colors.
Always look first to compliment your container and draw out the colors from it.
I'm inserting some of the flowers straight in from the sides, which is why you needed a higher lip of Oasis above the mug rim.
This Santa has taken on quite a jolly look - don't you agree?
