* Summer & Winter is fundamentally plain weave. This make it more forgiving than Overshot in designing coverlet-style cloth.
* It is woven with two shuttles, requiring tabby and pattern wefts.
* It creates a reversible cloth.
* It requires two shafts, usually 1 and 2, for the structure; however many shafts you have left, each one can create one block. So on an 8-shaft loom, you can have up to six blocks.
* In the first instance, they recommend warp and tabby weft yarns to be the same or similar, making the fatter/brighter/fluffier pattern weft the most visible feature of the cloth. Where/how the pattern wefts come to the fore creates the shapes/patterns in the cloth.
Threading:
Each unit has four ends, 1-n-2-n, where n is the shaft for this particular block. So, if a block uses Shaft 8, one unit consisting of four ends is threaded 1- 8- 2- 8. If another block uses Shaft 4 and is wider, say 12 ends, this is threaded 1-4-2-4, 1-4-2-4, 1-4-2-4. And so on.
Treadling:
So far, this has been the most interesting. With the same threading and tie up, but a slight changes in pattern weft treadling, you can get four different appearances. This is useful when changing the nuance of the cloth, or fine-tuning the corners of the blocks.

"Dukagang", perhaps the most familiar?

Tie-Up:
I'm guessing there is great scope for experimenting with the tie-up, but I can't think that far, so more later.
Material:
There are infinite number of interesting possibilities here. What I have in mind for the near future are are:
* Very skinny yarn for warp and tabby weft; thick, fluffy or loopy wool in pattern weft.
* Warp and pattern weft the same size but different colors, the tabby weft being very much skinner.
* Warp colors in gradation or stripes within a very narrow range on the color wheel, tabby weft in one of the colors, and pattern weft in strong contrast, perhaps complementary.

In the first instance, however, I used pencil in graph paper.
