Gave It a Good Try

I’ve given up on the Hullo pillow for a number of reasons.  1. If I was having a restless night the sound became annoying. 2.  I subtracted hulls and added hulls but never achieved lasting comfort.  3.  Where do I find pillow cases to fit? Unfortunately, I passed the return window of 60days, so I may turn into several small bags to heat for sore muscles.
