      Beautiful and perfect!!

      I love these covers. I have used them for at least 5 years if not longer. They are still beautiful and extremely functional. I am here to order more! Thank you for these jar covers!!

      Wool jar insulator

      I love these little guys. I want one for every size jar I have. Need to get more.


      These wool sleeves are just beautiful. I purchased each size as I ferment in all size jars. Each sleeve fits perfectly. The quality of the material and the handwork is exceptional. I live in an old, drafty house, and the sleeves will be very helpful through the winter. Thank you very much!!!

      Love these!

      These are so gorgeous! I LOVE how they look on my counter top, I was a little concerned they'd look weird but they look really classy! The little quote is such a cool touch. I really love how these glide off and on easily and make my ferments look subtle, like decor, instead of some forgotten mystery jar lol. Thanks Yemoos, will be back for more!
