Congratulations, you have successfully crafted an awesome halloween bat dream catcher! All that remains is to hang it on the wall.
Practical tip 1: for it to be effective, hang the dream catcher near the window (so the first rays of the day will destroy the nightmares captured during the night), or above the bed (so that the nightmares are caught more quickly )!
Practical tip 2: if it's a perfect dreamcatcher as a Halloween decoration, you can still keep it and make a great room decoration!
