I still wonder how idling tablets should help to avoid long floats. Didn't work with my experiments. Turning twice does help though. For patterns I still use a cheat sheat, but now I can see what is happening and often can avoid making mistakes or corret them.
I bought all three of Claudia Wollny's books! Great stuff. Last winter I found Egon Hansens tablet weaving book, but those scematics are nearly unreadable. Pictures are usefull though.
Idling tablets only helps to avoid long floats because it changes the way the twill direction is changed in that specific setup/process (which I guess you are referring to with your comment). Both idling and turning twice will mean a change in the structure, but more importantly in that case also a change in the sequence, and that change in sequence is the crucial bit (and will be the same change whether it's idling or double-turning).
Aaaand that is probably the most cryptic comments conversation ever to almost all the world...
