This is the perfect blanket for a picnic or celebration in the park as denim is very durable and lasts 'forever' - grass won't stick to it - folds up nicely and compact. The back is a neat checkered pattern of different shades of blue and white denim. Lots of time and care went into this one-of-a-kind Canadian Flag Denim Blanket. My mother designed and stiched together this beautiful blanket out of blue jeans. (I am selling it on her behalf) Any variation in colour or marks are just a reflection of the individual blue jeans they were made from. This is definitely unique and special.
