A practical example
Twin Leaf Bookmark — original authoring exercise
Start with
Four ordered units: R1, CH1, R2 and CH2. Rings each contain 16 double stitches; base chains each contain 12. R2’s first boundary joins R1.B.
Get this result
The base totals 56 double stitches; V1 totals 64. Only CH1 and CH2 change, from 12 to 16 each. Both rings remain 16 and the join remains R2 → R1.B. This is an authoring exercise, not a test-tatted pattern.

Own NerthaLace schema 1 JSON only. No TattingCAD .tat, photograph, image or antique-pattern import. IDs and picot names begin with a letter and use letters, digits, underscore or hyphen.
