I adhered them to an acrylic pane (16 x 20)
which was too scratched to put in a frame.
This is the finished panel.
I pasted them down with Liquitex Gloss Medium and Varnish.
A totally random choice in a loose grid.
I did cut one or two into 'leaf' forms to fill in some of the gaps.
The tissue crinkles but can be smoothed out.
Air bubbles were pricked and flattened to the surface.
There's that one brush drawing (lower left) from a previous post.
I painted the reverse of the plexi' with satin black Rustoleum.
I'll post more about this as I work on top of the collage.
