This pattern was written for the Pricewise DK which I think is pretty perfect for the job. It'll do for the oddments too, especially if you're making more than one (a FAMILY of Christmas sweaters!) or otherwise you'll get away with the Dolly Mix. You'll also need some 3.25mm and 4mm needles and some stitch holders.
For the girl's jacket you'll need 4, (4, 5, 5) buttons and for the boy's jacket you'll need 5, (5, 6, 6) buttons.
