JoLanda asked about waffle weave, how to do twill and waffle at the same time.
There are a number of options. If you want waffle and twill in the warp you need more shafts - here are some waffle options on four shafts. To make warp wise twill stripes, you would simply thread for twill on the other four shafts and then tie up and treadle accordingly. The draft above shows a lift plan because to do all the waffle options in one cloth on four shafts you run out of treadles and a direct tie up would be required unless you had a computer assisted loom.
Here is a 6 shaft version. This would make a very small 'waffle' and would not take up as much as a draft with longer floats. Therefore the difference between the waffle and twill would not be as great. Only sampling would show how much difference there would be. On a loom with 10 treadles you could tie up and treadle without having to use a direct tie up. Just add the twill tie up on the rest of the treadles and use them accordingly for weft wise stripes.
And lastly, here is an 8 shaft draft showing the tie up and treadling to make weft wise stripes of waffle and twill and would require 12 treadles.
I hope this has answered your question?
