Crochet Pattern For Confederate Flag?

I used:
Crochet hook G
Worsted weight yarn: Burgundy 1000 grams, Navy 500 grams, White 300 grams (Red Heart Comfort Yarn, sold in 454 gram balls, I used two plus a bit of the burgundy/wine/dark red, one 454 gram ball of dark blue/navy, and two 200 gram balls of white, with left over yarn. I also found that the use of "bobbins" or some other method of working with multiple colour changes useful)

Stitches used: Chain, Single Crochet, and Double Crochet

Chain 205 with burgundy
Row 1: single crochet burgundy in second ch from hook and in each chain after - 204sts. Chain 3, turn (Do not count chain 3 turn as a stitch in the row: each row must consist of 204 double crochet stitches, plus the chain 3) Remainder of afghan worked in double crochet, until very last row.

Row 2: starting in last sc of row, With Navy, dc in each sc for 24 sts, change to white, dc in next 3 sc, change to burgundy, dc in next 150, white 3, navy 24, chain 3,Turn (burgundy will be abbreviated "R" from here, Navy as "N", and White as "W". Therefore: R3, N4 would be use burgundy for 3 dc, and Navy for 4 dc, for example.)
Row 3: Starting in last dc of row 2, with N26, W3, R146, W3, N 26, ch 3, turn
Row 4: start in last dc of row 3, N28, W3, R142, W3, N28, ch 3, turn (start each row in last dc of row before, and end each with a ch 3-turn)
