I love stained glass windows, but they're very expensive and time consuming to make. I came up with a cheaper, easier way to create my own with no mess.
You're going to want to buy the waxy feeling tissue paper, not the kind you wrap presents in. It's a little more heavy duty, you can paint and draw on it without the paper ripping. Any craft store should have some.
First of all, get some inspiration: look up "stained glass windows" on Google, or check out a few books about stained glass from your library. Pictures of Tiffany glass works are my favorite.
Next, use your black Sharpie marker to draw out a window shape. Circles can be pretty cool. Or you can do the traditional Gothic window.
Use your ruler to keep the lines straight. Come up with a design or picture to draw. Simple designs are easier to color in. Also, remember that with stained glass, the lines are very angular--there's not a lot of rounded corners. The reasons for this is that rounded pieces of glass were harder to fuse together than squared pieces.
Cut out the window shape you came up with, and then pull out those colored Sharpie markers. The reason to use Sharpies over Crayola for this project is that regular markers will fade away when exposed to sunlight. Sharpie keeps its color for a long time.
After you've colored in your picture, tape it up in a window that gets a lot of light. You now have beautiful stained glass , without the expense. Another idea is to measure the window you want to put your design in and make it to fit.
