1) Wash your plate and dry well. 

2) Cut your thanksgiving image, apply glue to front, position on glass plate, apply a generous amount of glue on the back (lots).  Remove white paper backing from cutout. Slightly water down your Elmer's glue-all.  Apply thin coat of glue to the back of your cutout, let set for 5 seconds until the paper uncurls. Using your fingers work out all bubbles.  Let Dry, clean up with cool water and a kitchen sponge.

3) Prepare your letters.  I got some letters at my local craft store, painted them bronze, let dry, then I stamped the letters to get the look of fabric.  Apply glue to the front, position on plate, apply glue to the back of the letters, using your fingers work out the air bubbles.  Let Dry, clean up with cool water and a kitchen sponge.

4) Using Staz-on ink and a leaf stamp, stamp images on glass.  Apply pressure and roll the stamp around the curved surface.  You may want to practice on a blank glass plate.

5) Once the stamped image is dry, paint them with your acrylic enamel metallic paints.  Use a makeup sponge (cut into small pieces), and pat on the image, apply about three coats of thin paint.  You may apply glitter with glass medium for the first layer, then the paints.

6) Once Dry, and all glue cleaned from the glass, apply your background.  I mixed glitter with glass medium and sponged on a thin layer with a makeup up sponge.  Then add you paints.  I apply one thin coat of gold, then a thin coat of metallic green, and finally spray the back with copper krylon spray paint, and finished with gloss varnish.

Tips and Tricks:  Remember to keep your fingers wet and loaded with glue when you are working out those air bubbles.  Always work the paint on your glass in thin layers, don't use a brush, it will leave strokes, the best tool is makeup or fine sponges, with little to no holes.
