Interval calculator
Interval calculator
Spread N shaping operations over M rows, with no awkward remainder and no odd interval when shaping at both ends.
Settings
The depth over which the shaping is spread.
Number of decreases or increases, per side.
Row counter reading at the first row of the shaped section.
Direction
Sides
Rhythms
Two rhythms at most — that is all a whole-number distribution can ever produce.
Interval sequence
The two rhythms are INTERLEAVED, not stacked: the edge climbs evenly from the first row to the last.
Spread out
Grouped — avoid
The same counts with every short interval first: the edge breaks where the rhythm changes.
Intervals, in order
4, 4, 4, 6, 4, 4, 4, 6, 4, 4, 4, 6, 4, 4, 4, 6
Written out
Decrease 1 stitch at each end of every following 4th row, 12 times, then of every following 6th row, 4 times.
Row table
You only shape the edge OPPOSITE the carriage: the carriage sets the order.
