I am starting to collect wool to start an applique project. The majority of the wool that I plan on purchasing is overdyed and already felted. Should I wash the wool before I begin working with it? Is there a fusible that works well or better with wool? Can I use a bit of fabric glue stick to hold the pieces together?

What about marking? What is the best thing to use for marking since (I am assuming) the piece won't be washed when it is completed? Or should it be?

Thanks for the advice and help!
