Majacraft has upgraded the Little Gem and is now using bamboo in the construction of the drive wheel. Bamboo is a fast-growing, renewable wood and has the benefit of being able to withstand wide swings in the humidity without cracking or warping.
This is especially good news for those of us who live where humidity is high in the summer and low in the winter. My very first spinning wheel (not a Majacraft!) warped when the humidity increased in the summer, and had to be replaced.
The Little Gem upgrade is just one more proof that Majacraft is both committed to the environment and to making spinning wheels that will stand up to many, many years of use.
