Merry Christmas Lights

I know that duct tape and masking tape does not work, and do not even suggest nails. Is there anything else that will keep them up there?

I think you should get the Christmas lights that have hooks on them and stick them in the roof. If this does not work, try to polish and / or screws in the brackets and turn off the lights in the roof. Good luck!

Not only nails and staples.

Hold one end of the light and find someone else to hold the other end. Rest day.

A stapler works great. Good luck!

Why?

Staples might work ...

It will be so sticky it seems that it is self-adhesive.
