I was cruisin' the web today and found more free patriotic patterns in addition to the Patriotic Patterns on this site, for your stitching pleasure. If you start stitching these now, they'll be ready in time for July 4th!
Robin's Nest Designs features a full-color chart for both an American Flag (shown above) and a really nice Patriotic Alphabet that can be used to create your own personalized 4th of July project. Scroll down to the area just above their email sign-up area to access the patterns, and be sure to click on the "go to chart" links on the page.
If you are looking for patterns for your favorite person serving in the Military, free patterns for the armed forces are available at Military X-Stitch.com and that can be easily be converted to needlepoint.
