It is a Pottery Barn item from a few years ago. Looks like it sold for $199.

I hunted the late fall neighborhood garage sales and found a perfect frame. It was brown so I spray painted it cream.
I got out the trusty ol' staple gun. First, I stapled in the center on each side to make sure all was straight and then I stapled like crazy.
Here is how it turned out. I actually just used elecrical tape on the backside to make sure all stays in place. No need to spend a lot of time on the part no one sees!
To finish, I printed off (12) wallet size photos at Costco, one for each month of Grant's first year. I tied three rows of twine around the fabric panel and finally hung the pics with some mini clothespins I had from my card making days.
