Checking and Preparing Gutta Lines
Check gutta lines for gaps and thin bits and repair these before
painting.
Air bubbles do not matter, unless they clearly result in a gap in the
line. Check
every spot where two lines meet and make sure they actually join without
a gap
of even the smallest dimensions: the paint will bleed through the
tiniest hole.
Repair thin lines and gaps by drawing more gutta over the top. If in
doubt,
add more gutta to a line.
Test any lines you are not sure by applying clean water with a
paintbrush
inside the gutta line and seeing if it peeps out.
If any water bleeds through, you must dry the wet silk before
repairing the
gap with more gutta, because gutta will not penetrate wet silk, and
therefore
there will be no barrier to the paint bleeding underneath the gutta
line.
