Well, I have another idea that's perfect for Halloween.
Tada!: creepy cobwebs!
All you need to do is stretch the dryer sheet in different areas. Stretch them lightly or stretch them with force, let the ends fray...until they look like cobwebs.
Use them to decorate the front door, a window or a table.
If you don't have dark fabric, use a black garbage bag to line the table. Lay on your cobwebs and add your tricks and treats!
