This is the same glass ornament (with flat sides) that I used last year but with a new technique, which I'll detail below. The center poinsettia is actually paper, made from card stock using my POINSETTIA SVG file.
You can use any glass ornament but I prefer these flat sided ones as it is so easy to decorate them. For the poinsettia ornament I used strips of poinsettia printed tissue paper which I ripped into small pieces and then glued to the ornament with Glossy Accents. Once the ornament is fully covered with the tissue paper, I went back over it with a thin layer of Glossy Accents. Now to decorate the ornament!
Shown above are the pieces for the ornament. I cut the poinsettia layers using three shades of red cardstock. The darkest shade for the bottom and the lightest for the top layer. The leaves were cut from two shades of green cardstock. The gold medallion sticker came from a garage sale find and was the inspiration for this ornament's design.
Since the tissue paper had flecks of gold in it and the paper medallion was gold, the silver top on this ornament just wasn't going to do. So I brought out my Gold Mixatives alcohol ink and changed the color. After it was dry, I used some GA over it to make it shiny again.
To make the poinsettia lifelike, I got out my Distress Markers and the water pen. I edged the pieces with the brush end of Walnut Stain and Fired Brick, using the water pen to soften the lines. Notice the dark spot in the center of the largest red piece? That shadowing gave dimension to the bottom layer. I did the same thing on the middle piece, although it is lighter and doesn't show up to well in the photo. Once dry, I went over the pieces with the DM's fine point, adding the leaf veins. Once dry, I bent and curled each petal to give them dimension. I put the flower together using GA and then added Gold Stickles stamens to the center. I added more Stickles (Gold, Red, Green, Clear) here and there on the petals.
I attached the medallion using GA and once dry I used my finger tips to rub gold acrylic paint lightly over the entire surface of the ornament. Not to cover it, just to add gold here and there. It brings down the brightness of the tissue paper and gives an "antiqued" look. I used a round pop dot in the center of the medallion and stuck on the poinsettia...giving it even more dimension. Finally I added gold Stickles dots on the points of the medallion. I think it has a very vintage Victorian look!
