When I made a Raggy Jacket, I dampened it and then took it out in the yard and shook the daylights out of it and then brushed it for a long time. I then washed it in my top-loading machine. However, when I dried it, I stopped the dryer frequently, cleaned the filter well, and continued until the jacket stopped losing lint. Took a long time, but I have washed and worn it since with no problems.
