Crackle Treadled as Summer and Winter

I am done, for now anyway, treadling the crackle sample as overshot. I am now playing with Summer and Winter treadlings.

Summer and Winter treadling means that each treadling block consists of two pattern blocks. The pattern treadles raise two shafts, but the second set of shafts are not opposite the first set of shafts.

This means, for example, if I treadle to raise shafts 1 and 2 for the first pattern weft, I do not treadle to raise shafts 3 and 4 for the second pattern weft. Instead, I treadle to raise shafts 2 and 3 for the second pattern weft.

Each time pattern shafts are raised and the pattern weft passed through, then binder shafts are raised and the binder weft passed through. In this case, the binder treadle raises shafts opposite to the shafts in the pattern treadle just raised.

For example. I might raise shafts 1 and 2, throw the pattern weft, then raise shafts 3 and 4 (the opposite shafts) throw the binder weft. Then I might raise shafts 2 and 3 and throw the second pattern weft, followed by raising the opposite shafts (1 and 4) to throw the second binder weft.

A series of four treadlings thus completes one row of the block. This is repeated until the block is as high as I want it. I then move on to the next row of blocks which will consist of a different set of pattern treadles and a different set of binder treadles.

What I have just described. is what I have done in the following photo:

Here can be seen eight treadling blocks. But there are only four different treadling blocks. Treadling blocks five through eight are simply a repeat of the first four treadling blocks. The only difference is the pattern color order. In the first pattern treadle in each of the first four blocks I threw brown weft. In the second pattern treadle I threw blue thread. In blocks five through eight I reversed the order, first throwing blue weft and then throwing the brown pattern weft.

All the binder wefts are yellow.

These blocks form a nice diagonal line. This happens because the threading slants that way and I treadled in the same order as the treadling. That is, I treadled 1,2 and 2,3; then 2,3 and 3,4; then 3,4 and 4,1; and finally 4,1 and 1,2. Each of these treadling sets I repeated until each block was as tall as I wanted it.

Remember, by the way, the the warp is red..............

Peg I did click on the photo but I couldn't tell where the treadling errors are. I just thought it was lovely too see close up! I like the stepped diagonals.

I haven't studied crackle myself so I look at the overall effect and don't understand the details. I should think you are rather pleased with this?
