It measures 45 x 55".
On the back: a teal floral so pale that it was impossible to photograph accurately. So you'll have to take my word for it-- it's really pretty, if a little washed out looking.
Fabric availability warning: if you're thinking about getting some of this beautiful "Gallery Fiori" fabric for yourself, don't delay! I bought it at Hawthorne Threads, and recently got an email from them saying that the collection is going out of print. They still have some, though (click here to check availability).
