Analysis of The Patchwork Quilt

Here is this patchwork quilt I've made
Of patterned silks and old brocade,
Small faded rags in memory rich
Sewn each to each with feather stitch,
But if you stare aghast perhaps
At certain muddied khaki scraps
Or trophy-fragments of field grey,
Clotted and torn, a grim display
That never decked white sheets before,
Blame my dazed head, blame bloody war.
