Thanks everybody for your answers. This morning I went to a "brocante" here in Burgundy and bought a hemp shirt for 2 euro's. It's realy old and worn out, simply made and I love it. Wouldn't wear it though because it's very heavy and corse but the idea of using plants to make a fibre is so interesting. I am a wool spinner too and I have a loom. I like to make my own felt and of course quilt a lot!
Thanks again everybody!! Pinot
