Hemp fabric has made a big comeback in recent years. The most historical of fibres, grown and worn all over the world, over time it was replaced, or banned, or both.
Currently, the industrial cannabis sativa l. plant that hemp fabric and other products is made from is banned in the US. Significant amounts are grown legally in Canada, but we lack fabric production facilities so the crops are used in other ways, and exported.
Most hemp fabric in North American garments is made in China or Eastern Europe.
Hemp has numerous benefits. I love sewing it, and wearing it. It is the most eco-friendly fibre around.
