I typed a reply to you, Krystyna, about what you could do with the 100% Virgin Wool Samples but I don't see it here so will say again, haha.
Wash in hot water, dry on hottest heat in dryer and felt it! Then you can make a boiled vest (big money for these in stores) make a penny rug or table runner, use the felted wool to cut applique shapes for wallhangings (it doesn't ravel after it's felted). Lucky you! Beautiful fabrics and I got tickled at their line on their tag. Forgot what it said now but was cute.
