A DIY simple glass painting

It's always a crafter's dilemma as which craft to do first. I am also one such case who is shifting between one craft to another, abandoning the thing in between. I had bought a pack of glass colors with a plan to color the glass bottle, obtaining a  tinted  bottle. I abandoned this after not getting the expected results. After a few months again I bought a pack, this time of another brand, left it unused for many days.  Few days back I saw my relative using the glass colors to make a beautiful glass painting. I got so inspired from her and try a simple one on my own. So here a simplest way in which you can use the glass colors.

I took two drinking plain glasses.
Cleaned it first and let it dry.

I took Camel glass colors, Water based, which comes in a pack of six colors and a black liner.

Drew the desired design using the glass pencil. This is optional. If you are confident enough, you could do free hand directly with the liner.

With the liner that comes with the pack, drew lines, on already sketched design. I drew multiple diamonds around the curved surface of the glass.  Let it dry completely for about an hour.
I filled in these diamonds with the desired colors, one diamond at a time. The liner acts as a boundary and will not let the color spill to the next cell.

Since it was a curved surface, I had to fill each one and wait till it dried completely.While drying it again I had to lay it flat. Since glass colors run crazily, it would get concentrated at one place, look plain in some places. Its OK for the first time and its OK because making the paint stay on a curved place is not easy. But in spite of all these minor glitches the finished piece looked cute.

I used my terrace space for drying. It was sunny and was good for my project. This way the paint dried quickly and I could fill in each color quickly.

This is how it looks in the night
