I crafted this besom (maybe a bit early since Ostara is a spring equinox celebration) but the colors I chose represent the birth, or regeneration of the decayed winter season.  This is an ash broomstick destroyed by the ash borer beetle in northern PA. 
 
Yellow: stimulates the mind, represents an achievement, learning, happiness, completeness, psychic power.
Green: stimulates the mind, represents prosperity, fertility, love, romance, friendship, harmony.
Smokey Brown Black: illustrates the end but also a seed to a new beginning, riddance of negativity and negative thoughts
 
The overall length is 60"
 
All handcrafted by my husband and I for decor, however if you choose to use it for other purposes, keep it dry and out of direct sunlight to prevent accelerated fading.  I use non toxic Rit dye without preservaties to keep our products enviromentally friendly.
