Thin, uniform roots are strong and pliable when green or soaked in water. They can be used for basket weaving and to reinforce bark canisters. They are also used to sew bent wood boxes and besoms can be tied with roots. Even though spruce and birch roots are mostly used most roots will do.
Harvesting is best done in spring, roots being sappy and easy to clean from bark. They must be cleaned straight away or they will pick up color from the bark.
They are stored dry and soaked in water before use.
