I am about to embark on making hemp jewellery, but I'm not sure which size hemp to go for. Basically I have the choice of 0.5mm, 1mm and1.5mm, which is best?
Depends on what type of jewelry you want to make, really. Go thinner if you want thinner hemp jewelry (seems to be the most common kind to find) and thick if you want thicker hemp jewelry (thick hemp is often used for more masculine necklaces.)
