a child's sweater

About a year ago, Blue Sky Alpacas donated a bunch of their superbulky alpaca/merino blend to Afghans for Afghans, to pass along to knitters who'd be willing to make a garment. I got some of the yarn, missed the deadline for knitting at the time and felt miserable about it.
Another deadline came up and I finally managed to finish the sweater up yesterday and mailed it out to them.
The age group they are delivering warm winter garments and accessories to this time is 7-14, and I am hoping this 34" chest size will fit and warm an Afghani child.
I used 10 skeins and so the sweater weighed one kilo, that's over 2 lbs - nice and heavy.

Size 15 needles yielded a gauge of 2 sts/in. I didn't follow a pattern, but I checked my measurements against some size charts.
