How to felt?

[Nuno930]

I thought I knew how to do this... but now that the time is here (read: I finished my I CORD!) I am second guessing myself. I tried to do a search on here but there are waaaaay to many topics with the word "felt"

Ok so I put my garments in the washer--- hot water.

Do I use soap? For some reason I remember someone saying to use soap, but I could be crazy too since I don't recall that being mentioned here
