How to make?
I have used acrylic colour for the filling and pearl fineliners for the outline. OHP sheet is a transparent sheet used for presentation by BE students. It is similar to glass and can be used as an alternative.It is easy to store, no need to frame and also cheap. U get it at all stationary shops and it costs Rs.3 per sheet.(OHP= Over Head Projector) also called transparent A4 size sheet.
