On Tuesday, sacrebleu featured a post about FilzFelt, a company that sells products made of felt in addition to felt by the yard. Their website has a lot of information about felt, including a bit about how it's made:
"Sheep’s wool or wool fibers are continuously felted and compacted by moisture, heat and friction until a homogeneous fabric is formed – wool felt."
Isn't it amazing that wool from this sheep can be used to make pink felt or green yarn for a sweater, mittens, or hat? I'm guessing that sheep have been useful to people for as long as they've been around. Sometimes we look at animals and forget to be grateful for (and amazed by) all they have to offer.
