Water proofing wool
 

Has anyone ever tried to water proof wool & if so what did you use. I have a garden flag in my yard and have a few ideas as to what I want to make for it but they will look best in wool. I know I can get some cute ones that are very inexpensive but they are not what I want.

Never heard of it. How about encasing it in vinyl by making a pocket.

I found this: http://www.nikwax.com/en-gb/products...erproofing.php supposed to be alot by those who wear outdor wool climbing gear to keep it from getting wet.

I think you will have to be more concerned with the wool rotting in the sun.

Although sheep live outside in all weather, they are shorn annually.

nikwax is designed for clothing that will be worn outside for a limited time, not 24/7 in all weather.

Naturally water proofed wool comes from the way it is processed after the sheep is shorn. Some sheep breeds are very greasy and when the fleece is washed not all of the lanolin is scoured out. These sheep usually wear jackets to keep other vegetable matter out so vigorous scouring is not needed. The fleece is well skirted also. Some breeds of sheep's wool, like the finer fibered ones, felt very easily and this also helps keep the wool waterproof. Vigorous washing of a piece of wool cloth in alternating hot and cold water, and then a dryer will also cause felting which will help to waterproof. Go easy....you don't want to over felt.

Really? Make it in synthetic felt.

Essentially, wool IS waterproof. That is why sheep, llamas, etc. don't walk around with sagging wool. Tks. GiGi

After rereading the original post, I would not put a wool flag outside. It would not last long at all. The sun would fade it quickly and ANY wool would eventually absorb water that would take forever to dry, Slow to absorb moisture and very slow to dry back out.

Thanks to everyone who gave me much insight. I think I think I will just order the nylon flags and play it safe.

i'd use craft felt, cheaper and comes in more colors, at least by me it does.
