the spots are not intarsia. when i started on the sweater, i wasn't sure how many spots i wanted to make, or where i wanted to place them (or even how large i wanted to make them). so i decided to just do the whole sweater in red and then improvise a circle and figure it all out from there. the first circle i made was a pretty good size, so i made a few more and then decided on the placement - i just sewed them on as best i could! if you go to the flickr link in my first post, you can see a photo of the inside of the sweater, which shows that i sewed on the spots.
