This Corriedale is 29.5 micron, and a great. value priced wool. This fibre is great for wet felting, needle felting, beginner spinning and any use where a much finer fibre is not necessary.
The interesting thing about hand dyed fibre is the variations in the colours and how some dyes fracture and break into more colours. This results in more bang for your buck and a much more exciting fibre colour way.
Some felt artists I know wont buy commercially dyed fibre anymore for this reason, the variations in colour are unique and much more fun to work with.
