Ignorant Ruminations

I've been reading Claudia Wollny's Tablets at Work, while thinking about how she classifies diagonal and kivrim patterns.

She says that patterns using the diagonals technique can change the turning directions of 2 tablets at a time, every 2 picks.  These would be the classic Egyptian Diagonals method that is relatively common these days.

She says that kivrim patterns have some tablets always turning forward, while others turn forward and backward at 4-pick intervals to create hook-like motifs.  The number of tablets in the 4F/4B section(s) does not have to be a multiple of 2 or any other number.

Diagonal-type patterns use 2 colors, AABB, while kivrim patterns can use any number of colors and each tablet may be threaded with different colors.  There may be differences in S/Z orientation and starting arrangements of the colors within each tablet.

I believe that this categorization came about because of the book's way of summarizing techniques.  In particular, the tablet threading and starting positions are very important.  So the AABB one-direction staggered starting position of diagonal-type patterns contrasts with the any-color, any-tablet-orientation of the kivrim-type patterns.

Hmmm....

I think that I would generalize diagonals to include any kind of change in turning direction of individual tablets, in a way that creates hooks, spirals, diamonds, zigzags, meanders, waves, rhombi, etc. due to the threaded-in colors. (yes, this slightly overlaps with double-face, but I don't care.)

Kivrim would be one sub-type.  Egyptian diagonals would be another.

A third sub-type would be Finnish diagonal patterns, where any individual tablet might change turning directions in any pick.  Half-turns are also allowed.

Another sub-type, perhaps, would be modern patterns where some or all the rules are followed or combined or broken at will in order to create an interesting result.  These would include some of the GTT and similar patterns that can be found on pinterest and elsewhere.

For any of the above, twist may accumulate or it may be balanced.  For patterns that accumulate twist, the weaver may also balance the patterns by deliberately reversing the motifs at regular or irregular intervals.

There is another sub-type, which overlaps the above.  That is diagonal-type patterns that involve tablets changing their turning direction, but which are balanced.  In other words, the number of forward and backward turns are equal over the pattern repeat.  After every pick, any number of tablets may change directions -- it doesn't have to be an even number of tablets or an even number of picks.

The simplest ones, possible a sub-type of the above sub-type, are 4F/4B or 8F/8B patterns where different sections stagger the rows in which the forward and backward turns begin.  In other words, tablets 1-4 might be 8F/8B while tablets 5-8 would be 4F/8B/4F, and so on.  The tablets are often but not always groups of 4 tablets.  The offset might often but not always be one half to one quarter.  Although the AABB staggered set-up of Egyptian Diagonals is common, I don't know if it's required.

I mention this particular turning pattern because I've done one like that before -- the Running S band.  I'm considering another one in this style that is a bit more complex.  Before I warp that one up, though, I might do a double-face sampler band.  Or I might do the classic Finnish S pattern.  That one falls into the Balanced/Offset category -- 3 tablets are 9F/5B/5F/9B and the next 3 tablets are 5F/9B/9F/5B.

Several other patterns in Applesies and Fox Noses are balanced/offset.  Several are balanced though not offset.  Some are not balanced at all.

Hmmm...  More thinking is necessary.  Plus more weaving and more charting explorations.

I'm sure my thinking will evolve as I gain more experience and as I explore more both in these weaving techniques and in other complex/advanced weaving techniques.  But this week I am intrigued by the complexity of designs that can be generated with simple, regular balanced/offset patterns.  Plus they're easy to weave since there is no build-up of twist.
