This is a pattern that I’ve been thinking about for years. It wasn’t until a discussion about the RS equivalent to a WS pfb, that I finally had the answer to how to make this pullover look how I wanted it to look.
It has an unusual construction. It’s worked from the top down -- starting with a doubled ribbed collar. (A provisional cast on is used in making the collar.)
It has a modified raglan design in which body increases are worked first, followed by sleeve increases. This gives the look of set-in sleeves -- without the bother. ;)
And, it has diamond patterns down the front.
