i wash all of my wools in hot hot water!!! rinse in cold=then dry in a hot dryer- when they are done they are (felted) do not fray- and thick- luxurious- and will no longer shrink-
i go to yard sales- thrift stores and shop for wools all the time- they always go into the washer with the hottest water i can get- i usually heat my tea kettle and add boiling water too-
then the wools are ready for what ever you want to do with them=use for a batting- use for appliques- use for piecing- use for clothing-
i love working with wools=
they are wonderful to (over-dye) and wash up beautifully!!!
once they are felted they are done shrinking- then they are ready for what ever you want to do with them.
