Versatility plus
Color: Boquet Hearts Red
This throw is more substantial than some I have purchased. It is well made. I love the hearts! I use as a topper to cover Christmas quilt and takes us through Valentine's Day! Feels great against your skin, roo!

Beautiful throw
This throw is large enough to cover most of you and is very soft. The print is beautiful. It's actually prettier than I expected. It came out of the washer and dryer in excellent condition. This throw is a really good value for thekney.
