After the wool is spun into yarn, it must be dyed to produce color. Natural wool is transported to the dyer where two types of dyes are used. Synthetic dyes are chrome based, give a huge variety of colors and can be consistently reproduced. Natural dyes are extracted from plants and minerals. They provide a wide range of colors, some of which are difficult to achieve with synthetic dyes, and are nearly impossible to consistently replicate. We use Swiss chrome dyes in our carpets to provide color continuity between rugs as yarn is dyed as needed, not stored in huge lots. Dye lots are hung out to dry, bundled, and transported back to the weaver where they are rolled into skeins in preparation for weaving.
