220 felts great. I think felting duration, so far for me, has been about the same as WOTA.
I haven't noticed any color bleeding into the water when using 220. I had 1 pair of WOTA clogs bleed into the water,
haven't bought white. the lightest 220 I've used is a bright lavendar.
honestly I'd use WOTA all the time if they had more colors, since 220 yards of WOTA is $3.58 compared with 220 at my LYS for $6.60.
