Abstract: An apparatus for containing natural fiber comprising a flexible shell and one or more straps secured to an outer surface of the shell for cinching the shell closed. The shell preferably comprises low-density polyethelene, and an openable end to allow access inside the shell. The shell may be substantially transparent to allow for viewing of the contents of the apparatus. The openable end of the shell may comprise four flaps, wherein the straps hold the flaps closed when the straps are cinched. The shell may have a generally hexahedral shape when full of wool and cinched closed. The shell may comprise gussets built into the end opposite to the openable end for maintaining the opposite end in a generally rectangular shape. The straps preferably comprise woven polyester. Each of the straps may comprise a free end and a loop at the other end, whereby a half-hitch can be tied to the loop using the free end.
