So, I've felted sweaters before for small sewing projects without any real issue. This time I decided I wanted to felt yardage because I want to make a little boiled wool coat for my son. Well, I got a 98% wool fabric at Joann's washed and dried it on hot about 5 times. My research on the internet seemed to indicate that a 98% wool should felt fine. It felted, however it has come out a little uneven. Parts of it shrank perfectly and lay flat, but then other parts rippled. The flat and ripple parts are very consistent and run in lines parallel to the selvedge each being about 3" wide, so the fabric is now striped in a way. This is really seems to be an issue related to how the fabric was woven based on the consistency (even though it is so weird how consistent it is).
I've thought about taking an iron to it with lots of moisture and steam. I'd put a wet towel over it anyway to iron the wool and prevent it turning shiny on me.
I'm not sure how to fix this, any ideas?
