I live in a very windy area. I go through flags quite often, if the wind doesn't get 'em the sun does (summer runs from about 110-118 degrees). This Betsy Ross Heritage flag is very heavily constructed, four rows of stitching across the end should be helpful against our ripping winds. Stripes are double stitched, stars are embroidered, and though I'd prefer triple stitching on the stripes, the double stitching will hopefully withstand the strain.
Note: Although this flag is listed as a 3x5 I can attest that it is larger, not 4x6 but larger than your standard 3x5, either that or I got an odd ball, either way ... I LIKE IT!
