These hand sewn sprout bags are approximately 12×16 inches (30x40cm), see below. This is a much heavier muslin that we had to source outside of the USA.. They also have a heavier drawstring for larger tasks. This bag is ideal for protecting roots in all gardening applications including storage.
The finished dimensions are about 1/4 smaller in either direction and will vary from time to time. This is due to natural properties of cotton and the manufacturing process.
