I had tried to make one before out of twigs and a stick for the handle, but I forgot to dry out the twigs and then was afraid of them snapping. I got the idea for the grasses, I wanted to use straw, when I was looking out the window at the field behind my house. There was a large patch of golden, straw-like grasses just behind my fence and I thought that they would make a great besom! So I went outside and pulled a couple handfulls, after explaining to them that they were to be used for magickal workings. I got my bundle and went back inside. I placed them side by side on the floor, bristle tips alined, and cut them all at about the same length. I wrapped them fairly evenly around my stick about 6” from the end. Then I started wrapping string tightly around the bundle starting 3” from the edge of the cut off straw. I wrapped it until there was 5” of wrapped around yarn holding the grasses firmly in place. All together it’s about 4’ tall. I still need to cleanse and consecrate it, but at least it’s made now.
