Very nice sheepskin .
Size: 2' x 6' (Sheepskin Pelt Patchwork), Color: Wolf Tipped
This rug is very gorgeous , nice soft and plush. The wool is upright and even and you just want to keep touching it. It had some odor at first which is now dissipating the longer it is aired. Well worth the price. However I ordered two different colors at the same time. This is the one that I received first and am still waiting for the second one in light brown . For some reason the other was stalled somewhere in Kentucky as of this morning and upon communication a replacement was ordered by Amazon. I'm very happy with this one , just wish the frustration hadn't arisen over the shipping for other and will update or rate after I receive that one.

Beautiful in a window seat
Size: 2' x 6' (Sheepskin Pelt Patchwork), Color: Ivory White, Size: 2' x 6' (Sheepskin Pelt Patchwork), Color: Ivory White
This is soft, pure white, and of decent quality for my purposes. I saw a photo of one used in a window seat so that's where mine is white 3 lumbar pillows on the sides and back of the seat. The size is perfect. It's a little bigger than my seat so I could use the tape to pin one side to each wall and also over the seat. I guess it all depends on what you are using it for to determine if you'll like it. I have a large sheepskin rug in another room. This one in my opinion is too skinny to be used as a rug. I haven't detected a smell at all.

It's real!
Size: 2' x 3' (Sheepskin Pelt Patchwork), Color: Ivory White
Off white but totally happy. Even though it's wool, it doesn't itch and is very soft. The patches are few and not at all noticeable from front. Very thick and looks great!
