How to give a nice finishing touch to your cyanotype on glass.You can use a transluscent polyester paper sheet (optionnal) and another clear glass plate to protect the back (see also my orotones).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 on the side 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 !If you hang it, make sure you use a clamp strong enough…With larger plate you’ll need to cut a stripe for each side.
