Etched Glass Smiley Face Coasters

In drinking a depressant like alcohol, I find that a smiley face is benefit.  I found some old yellow glass rounds and thought that I could happy them up.  This is a really simple project, but it requires you to fine-tune and tweak the image you will use.  I made this using the laser cutter at TechShop.  WWW.Techshop.ws

The first step is to find an image of a smiley face.  I just did a google search and chose one of the smiley faces, copied, and pasted it into coreldraw.

I pasted the picture into coreldraw and adjusted it to the approximate size of the glass round.  It doesn't have to be exact because we are just going to raster the smile and eyes onto the glass as opposed to a full etch.  

You will have to convert the image several times in order to be able to remove the unnecessary parts.  

You have to use the outline tool to remove parts of the image.  

Now you have to repeat the previous steps until you are left with just the smile.  Instead of selecting the yellow background, you must take out the boarder circle as well as the white background.  

Once you have everything set, etch it into the glass.  

Test etch into some scrap wood so that you can line up the image under the glass.  Make changes accordingl
