Establishing the grain of your glass is just as important as picking out the colors for your project. Even the most perfect color can be ruined by bad grain direction and nowhere is the grain more important than in the sky or the background of your piece. Too often I see the lines marked on patterns haphazardly. Yes, they give a general direction but when your pieces don't line up your entire window is off. Below is a perfect example of bad grain lines. They run horizontally but they should run perfectly from the 9 to the 3 position on a clock.
This is a variation of an old Swan Hand Mirror pattern that I found in a book decades ago (literally). When Cindy wanted to make a Peacock Hand Mirror I figured that the Swan would be a good starting point. I just altered the head and the handle and it was done. While looking through old projects Angie stumbled upon the pattern and knew she had to make one. She got it all cut out, ground, wrapped, and tacked together in one class which means that when she comes back in she'll be able to insert the mirror , finish this and start on something new.
