I had lots of fun using glass stain on its own to repurpose a bottle and decorate it to use as a vase. However, I really found the beauty of glass stain only after I used it with the Glass Stain Leading. I used the black Glass Stain Leading to outline the designs and create custom, ornate, stained glass art. It was easy to use the leading similar to a pen because of its tip, so I had fun doing the design on each side of this somewhat square glass container that I bought. The different coloured glass stain I used really shows through this thick glass once it is filled within the leading, and is confined to each section. I love how the project turned out. I am looking forward to do more glass stain projects using both glass and clear plastic.
