Re: skins,
My kit didn’t come with the bag to put the skins in. I wound up using a similar type bag my wife had laying around, but I couldn’t close it correctly and when I looked the bucket the following morning it had opened and most of the skins were free floating. I decided to just leave it and strained them out later during racking. Worked fine.
Also, I’ll note that my bentonite packet also didn’t dissolve all that well. It reminded me of clumped up cat litter. I eventually just gave up and figured it would eventually breakdown itself. When I racked the bucket there weren’t any clumps, so I suppose it’s not terribly important in any case.
