Here's a link to stars and stripes forever- This picture is older than a couple of days but it's stars and stripes. Is this what you are looking for?

It's in Judy Martin's Knockout blocks which is no longer in print. It can be found in some software package. The pattern can also be found in Quilter's July 2002.
Whoops! Link already posted so stars and stripes isn't it.
