For those of you looking for an alternative to wool, but are tired of the same old boring cotton, this one is a no brainer! Bamboo is a natural anti-bacterial fiber. Viewed under a microscope, the pores of the fiber are closed, resisting little bugs by nature. Couple this with the strength and durability of silk and you have a lushes heirloom that will stand the test of time. Available in 3 weights for your stitching pleasure.
