and another view 
Four different yarns, ranging in age from "just bought" to 40 years. Blue: Bernat "Sesame" from my mother's stash. Red: Ella rae Classic, maybe a year since I bought it, leftover from making solid red regular socks. White: Cascade 220, purchased online, arrived the day before I left. Cream-white: Cascade 220, purchased earlier this year or maybe late last year from yarn store: it's the ribbed stripe near the top.
Ignoring the narrow white "filler" stripes top and bottom, there are 13 red and white stripes (7 red, 6 white between them) of equal width, as on the flag. I have lots of leftover red yarn (and balls of red yarn waiting to become pairs of red socks) and bought the white because I didn't have enough cream-white.
Naturally this pair is named "Fourth of July" and is the fourth pair of shorty socks I've knitted this year. I put them on only for the pictures; they won't have their first day of wear until July 4th. Since I have more red extra yarn than any other color, I'm also going to make a pair with red framing (where the blue is on these) and blue stripes. I don't have enough of this blue to do two socks, but I have other blue yarn.
