Rambouillet is incredibly similar to merino wool, but not the same on the genetic level.
These packages offer you four different base colors of rambouillet, undyed, or overdyed with the same color. Packages weigh nearly 4 oz. No package weighs less than 3.8 oz. Each color has a different micron count, but all are incredibly soft. Only the cream colored base is combed top; the rest are pencil roving.
Lani's Lana sells them as individual 4 oz bundles. The colors are Dust, Cloud, Storm and Thunder.
