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.
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.
I was moderator of a rug group of nearly 3000 weavers all over the world for decades & this is the first I have heard this. The group is no longer viable due to platform sell outs & tech issues many decades ago however I was very much in touch with the community since everything posted went through me in order to keep us safe.. Experience is a good teacher & it is in the sharing that new avenues for experimentation are open. Thanks for sharing your successful experience.
Just wanted to add that the little wool rug in front of my shower stall has completely felted from years of wet feet and pressure. Love it !
