How to : les finitions

How to : give a nice finish touch to your cyanotype on glass.

You need a transluscent polyester paper sheet and another clear glass plate to protect the back. And most important : wash your hands!
You can use black washi masking tape. I usually cut it 1 cm wide, but it depends on the thickness and the size of the plates.
Put carefully your glass sandwich in the middle of the sticky tape.
At the end of each side, cut the tape to fold it nicely.
And go on with the four sides of the plate.
Cut and fold the last part of the tape and... voilà !
The opal polyester paper allows the light to go through but no background.
If you hang it, make sure you use a clamp strong enough...
