I was delighted to find that I still have the relevant pieces used in the construction of one of the prototypes. Taking inspiration from the old Empisal manuals, I demonstrated this process with a doll for the model,
This prototype was made using interlock fabric, just the collar piece being knitted in a simple 1x1 tuck stitch. The neck band is attached to the back neck, and the top sections of the front pieces.
These are the pattern pieces, the equivalent of schematics for an all knitted version
The pattern pieces were based on a cling wrap body wrap, discussed earlier on this blog, an excellent method for accommodating all shapes and sizes,
I'm not sure this illustration adds much, but it really is a magically useful process.
edited to get back to the detail of how to work out the slant on the fronts of the cardigan.
The black lines represent a standard, one piece front. The sketch shows shaping at the sides. Yours may or may not have shaping.
The red lines illustrate the adaption for one side of the cardigan. (The other is a mirror image) The upper edge is defined by extending the neck edge across to the lower edge of the opposite armhole. The free side need not be shaped, even if the seamed side is shaped.
On the cardigan used to illustrate the pattern download, the neck piece is knitted in Passap Long stitch, and doubled over to cover the cut edges of the main pieces. It is a design feature of this version to have the neck piece longer than the edge to be covered, giving a pleasant asymmetrical vertical to the garment when worn.
My most recent outing of this design was this T Shirt, altered to add in a knitted half front in stocking stitch, and a neck piece in 1x1 tuck stitch. This time the neck piece is sized to match the length of the neck and top edges of the cardigan.
I started this posting on a Mac, and am finishing on an iPad. The format has slipped from my control somewhat. I may be able to sort that out some time, but I will publish as is, in the interests of immediate optimistic explanation..
