Hmmmm.
No first hand experience, but here's what I'm thinking:
I'm not sure if the scallops or the waves on the rotary blades are deep or pronounced enough so that when washed and fluffed you'd be able to notice the scallops; would the raveling just obscure those curves - making it look like a regular ragged edge?
It certainly wouldn't harm or screw up the blocks, but you can easily do a test sample to see what exactly will happen.
Good luck!
