Step 1: Tumbleweed Shopping
Step 2: Score!
I gathered a few different kinds to have the best selection. Most tumbleweeds have leafy remnants and spiky protrubances that could require more cleanup work, so I suggest finding the smoothest one possible with the least bugs living in it.
Step 3: Cleanup
Next I snap off any unruly branches that jeopardize the overall shape. The bottom has an extra long stem so I took a little hand saw and cut it down.
Step 4: Lights... Camera... Action! (sans the camera)
I attached the wire of the lights to the branches with a few gator clips, since that's what I had lying around. They seem to have held up nicely so far.
Step 5: ¡Voila!
Therefore the most MacGyver style method I could think of was to affix the chandelier to the ceiling via staple gun, which has actually proved effective so far.
And voila! A super simple tumbleweed chandelier.
