The colors are a bit odd in the photo, the blue is a rich dark navy, the brown is a russett, sienna type brown, gold and a great coral, melon color, the colors are much nicer than the photo shows, darn.
There is no pattern, I just knit and changed colors at will.
Here is the inside, the technique is sometimes called 'Norwegian stranded knitting" the colors of yarn are carried across the back of the work, it actually creates a double layer of wool making this type of knitting decorative and very warm.
My mother was taught by a Danish woman who called it double knitting. Anna was a prodigious knitter, always turning out amazing creations, I am fortunate to have one of her Scandinavian style sweaters.
Anyway I will order clasps/closures for the front of this little sweater and put it away in case I ever have a grand-kid!
