I just finished weaving a 24" X 36" rug - wool on a linen warp. I am wondering if I should wet finish the rug. It is woven at 6 epi, the wool is old wool of my grandmother's so I am not sure what the weight is but the weft covers the warp. I could only find one comment by Jane that said most weaving with the possible exception of rugs needs to be wet finished, so I am just not sure.

IMHO Rugs are usually very tightly woven on looms designed to take high tension and very hard packing.. I don't ever recommend washing them. Use a soft bristle broom to sweep them or light suctioned vacuum. Some weavers hang them securely and beat them( not something I've ever done except on tightly woven cotton throw rugs) If you live in a clime with snow - you can put wool rug in fluffy (only) snow once or twice/yr & brush it well with a broom. You will see all the dirt removed on the snow. Allow the bit of dampness on rug surface to dry then replace rug in your favorite space. Professional cleaning should be considered for serious spills & stains that are not easily removed.
If a rug is soaked then one might assume the warp is too. A rug would need to be completely dry within so as not to rot the warp over time which is a consideration for a rug woven using any material.

Interesting information!
I had no idea. I will file that away for when I make rugs!
Thanks!

I have woven wool rugs in my bathroom right now that I took off the loom 20 years ago. All have linen rug warp. Similar dimensions to yours. I have machine washed and dried these many, many times. Yes they shrunk at first, but it added to the squishy wonderfulness.
