The following guidelines are applicable to most textiles - I have created a YouTube video, or you can check out the notes below.
Here are the basics when thinking about where to hang your tapestry.
I usually use a 3M Command Sawtooth Frame Hanger, as you can move them around, and they won't damage the wall.
1. Avoid hanging your work in direct sunlight - light is not kind to textiles, as it will fade them.
2. Avoid moisture - textiles will suck up moisture, and attract dust, so ensure the area is dry.
3. Avoid smells, as your textile will absorb smells - for example: cooking smells, open fireplaces, etc.
4. Check your artwork from time to time to ensure there are no bugs or spiders in there. The wool I use has been pre-treated for moths, but you never know what is lurking around, and prevention is better than cure!
How to clean your tapestries
All houses get dusty - you have to clean all artworks in your home periodically, and tapestries are no exception.
1. Give them a gentle shake - I don't mean bash them like a rug, but just take them down, and shake them gently outside to disrupt any dust that has settled.
2. Vacuum them! This is what I do - I just put a piece of muslin over the vacuum cleaner nozzle, and gently clean the surface. You can check out my video above for how I do this - works a treat!
3. If your textile art is damaged, then you can contact the artist, or if you don't know who the artist is, contact a textile conservator. If you can't find one, your local art gallery should be able to point you in the right direction.
Tapestries have been in collections for hundreds of years (some for thousands!), and there is no reason yours can't be too ... but you do need to look after them, and be mindful.
Good luck, and please contact me if you have any questions!
