Hello Sunitha, For any decoupage art take the cutouts of the required design & paste it on any base using fabric glue.than decorate the outline with liquid embroidery pearl colors or glitters as per ur requirements,so that the design cutout will be covered & not at all visible like a greeting card or a calendar or a fabric cutout.
You get glass pencil markers in any hardware stores. you may get them in White or yellow colour Our regular CD marker pens can also be used on glass The best way is to TRACE the design on the glass using white, yellow or any other coloured carbon paper as per your requirement.
Oh ok, will try. Thanks a lot.
