Moths!

I have a fine wool tapestry that I want to use as a wall hanging. Is there a way I can discourage moths getting to it?

What a fantastic question! I would pin strips of cotton tape down the back, which have been soaked in a concentrated blend of Tea-tree and Citronella with Geranium added to disguise the scent.

Once every two months use a soft toothbrush dipped in the mixture to run down the back of the tapes to reactivate it. You would probably be safe in simply spraying the back of the tapestry but as I suspect it may be valuable I would take the extra precaution of using tapes.
