I usually don't like doing it because I find it a bit fiddly. But since I knit continentally and I also know how to throw, I thought I'd give it a whirl with a strand of yarn in each hand and it works for me quite well.
[BTW: Awhile back in a crafting group that I attend, someone who knits and is from another country stated that I must be a very slow knitter. I asked her what made her think so. She then said something to the effect: "You're American. You throw." Assumptions aren't cool, people. Not to mention, there are fast knitters and slow knitters. It doesn't matter how you get there. /BTW.]
Anyway, I grabbed some Brown Sheep Naturespun Sport--one of my faves for this type of thing, measured Loretta from neck to mid-back and from under arm to under arm and came up with a measurement of 7" x 7". I figured out my gauge and how many to cast on, found a simple fair isle pattern with a multiple of 4 and got going.
Since I like working stranded colorwork in the round, I added a steek so that I could later cut it and end up with my 7" square.
After that, I made a ribbed section that will connect the two sides together and finish the body. I just sewed the ribbed rectangle to either side of the steeked portion (I tacked down the steeks to the underside first), leaving openings for Loretta's little legs.
Loretta loves her new sweater. After all, she hardly has any hair, poor thing.
