My neighbor has a parrot--a conure--that I sometimes take care of when he is in Disney World. (Seriously, if he's away, he's in Disney.) They live across the street. It's a normal street with houses set back thirty feet or so. And still I can hear his parrot screaming...sometimes even when I am in the house with the door closed. Apparently this has a purpose in nature and since parrots aren't truly domesticated you get the screaming.
I am guessing this is why Dawn Bradford named the pattern, "That Dern Parrot." She either lives with one or visits one. Or saw one once in someone's home. My parrot, who is always silent, never poops on the couch, and doesn't bite, also has much more muted coloring.
I've now completed the main stitching, and the next step will be to do the chain stitching on the front and the back. This is finished as a mattress-style cushion and there is some small amount of stitching on the sides as well. The main part is done.
