I got the pattern free from the burdastyle.com, their version is unlined but raw edges make me nuts. It is made from an india cotton summer spread remnant and lined in muslin it is huge.
Gorgeous fabric, makes a wonderful bag - Have you thought about putting in a flat bottom? That would make is not so deep...
I have been having issues with the site too. I tried to download the pattern, but the file could not be located.
I've been having that same problem for a few days
