My apologies for not listing the felt content...I'm pretty sure it is synthetic, and definitely not wool. Whether it's a blend I cannot tell. Felt is something I am unfamiliar with.
OK...I just now did a sniff test...and it does have a bit of a wool smell to it. It is heavier that other felts I've sold here. So, I am going to have to say I do not know the content of this felt. It came to me in a package of other fabrics.
