First, get a bunch of cotton buds (or Q-tips, as some call them) and cut them into halves.
Next, poke them into a Styrofoam ball, evenly spacing them out. Be sure not to place them too close together, or they won’t push down very far.
Then, dip the cotton tips into some food coloring or paint. Next, snip the stem off some unwanted fake/plastic flowers and poke them into the ball (you may have to hot glue it to keep it in place).
Finally, pop a few of these flowers into a jar, stand back, and admire!
