Playing eco print is fun. Joy of unbundling is like opening a present. (Sometimes something may not as expected). This piece of chiffon I intended to do the tie marks across. It did turnout as what I want.
Pictures speak themselves........
Shades of eucalyptus leaves, some with iron mordant some were not.
Different strings have different sorts of marks
A soft chiffon scarf with shades of euc leaves and tie marks is done.

Steps of making : I folded the fabric like croissant and bundled the whole roll with strings along.
Tips to make the string marks: First to tie with rubber band then roll up the bundle tightly and tie a knot in the middle. Hold the bundle against the table with one hand and the other pulling the string. The pot should have some leaves or rusty iron so that would make the tie marks.
This scarf was a piece I demo in Portugal.
