Keeping in mind that I am using the same threading and tie-up, here are two more versions you can do with single two-tie (summer and winter) just by changing the order you treadle your tie-downs.
Dukagong fashion using the tie-downs in 1-1-1-1 order.
Alternate fashion using 1-2-1-2 tie-down order.
So far with all my examples, I have used the tabby order in a-b-a-b order. The main thing to remember is that once you decide on the tie-down and tabby order you will use, you should use them throughout the entire project. Unless you don't want to and like what you get!
