Why do people mix merino roving with C-1?
The blend makes a fantastic all-purpose felting wool. C-1 gives durability and structure to the mix so it will wear well over time without pilling. And merino makes the mix felt at a faster rate and fills in the spaces between the coarser C-1 fibers, resulting in a very strong but flexible felt. C-1 also add a slight sheen and using both wools means you have endless color mixing possibilities.
