So, I saw a picture of a Hochdorf band woven by a member of the Historic Tablet Weaving group on Facebook. It looks like you can get more detailed patterning with this technique and you also get a nice sort of pebbled effect in the background weave.
Anyway, so I googled it and found this webpage The Warp Factor, with a nice explanation of how to weave this band and a good diagram to go with it that tells you exactly when and where to turn the cards. Nice stuff.
This is my second attempt at Hochdorf patterning. First was in acrylic to work out the technique and the use of the board. Second in 2/60's silk, to make something extra special nice.
This is my new weaving board. It's a bit scrappy but it does the job. there's a few wee annoying problems with it, but the next one will be better.
This is how tension is maintained on the band, with a nice even consistency. The main part of the band is held as one with a bag full of weights. The selvedge tablets however are twining continuously in the same direction, so they need to be weighted individually in order to remove the twist
To understand the threading diagram you need to know which hole is which on the cards. You can see the woven band on the right there, which will of course be on your side of the cards.
This explains what I mean by S and Z card direction. As you see, S and Z both have a diagonal component, the thread follows in the direction of that component.
Of course, it's not for nothing the S and Z threading direction are called that, as there is an already established method of indicating the direction of the twist in a yarn, as you can see.
So this is the full threading diagram for this band. I have an extra selvedge card on each side of course, as this is very fine stuff. As you can see there are only two holes threaded in each card, and the cards are threaded in a manner whereby two cards are threaded together as S and the next two are threaded together as Z. These cards are also then turned together and you'll see that when you take them together one is threaded in holes A and C and the other in B and D. This means that together they make the equivalent of 1 card threaded ABCD.
So, in order to weave, you turn two quarter turns for each pattern step. From this position if you turn forward you will get white, and if you turn backwards you will get Blue. Following this you'll see that The positions of the threads in the cards has reversed, so if you were now to turn forward you would get blue, and if backwards white.
So, if you want to weave continuously white from this position you do two quarter turns forward, then two quarter turns backwards.
This is the basic threading draft for the pattern, along with an explanation of the terms used. The actual turning diagram is on the page I linked to. The only difference is that I believe she threaded her cards the other way from how I did it, so if you're using my threading diagram and her turning diagram, for F read B and vice versa.
You can probably follow the turning diagram exactly if you were to swap the blue and white threads around in my threading diagram.
I'd add my own turning diagram for this band but I don't yet have the means so you can get the turning diagram at The Warp Factor
