I'm insulating my Lavender Boutique/workshop with hemp batting.

The space is a 10'x12' section of a pre-fab Amish built 22'x12' barn.
I've lately become very aware of and disgusted by the general toxicity of building materials and the amount of waste generated and am striving to use more sustainably responsible products.
I really don't want to use a vapor barrier of plastic sheeting and after the last comment in this thread have decided to just staple heavy canvas in my color choices on top of the hemp.
This takes plastic, dry wall, tape/paste, sanding, paneling, paint out of the picture.
