This dream catcher inspired, blue selenite wall hanging is 23 inches long. It has 3 unpolished selenite sticks that are roughly 8 inches long. Cotton and acrylic yarn in various shades of blue. Colors differ slightly from photos.
 
Gloves are recommended while handling. Handle with care. Selenite stones splinter extremely easily, it makes a huge mess. Keep out of reach of children. Use sturdy fixtures for hanging this dream catcher. Selenite stones are too heavy for a single tack.
If you must dust this, I would use a vacuum hose with a brush attatchment, vent open to reduce grab.
