Start with a blank page.
Draw two roughly parallel squiggly curves from the top center to lower left corner.
Draw progressively smoothing curves roughly parallel to the originals moving outward to the edges of the page.
Introduce slight expansions and contractions as you see fit.
No curves should cross.
Leave the space between the origin curves empty.
To the left of the left origin curve perform these operations on the sequence of laminations: Hatch with perpendicular evenly spaced lines | Fill | Void | Void | Fill | Void | Fill | Hatch with upward slanting evenly spaced lines | Repeat in reverse | Continue with variations on this theme till end of page.
To the right of the right origin curve these operations on the sequence of laminations: Fill | Hatch with upward slanting evenly spaced lines | Hatch with downward slanting evenly spaced lines | Fill | Void | Hatch with perpendicular evenly spaced lines | Fill | Void | Void | Fill | Void | Repeat till end of page.
