I use royal purple marbles for the owls eyes so they really bug out, and a nugget for the body. I wrap each piece of glass in lead came, fabricate all the details, and solder it all together.
The little owl measures 2.5 inches tall and 2 inches across (6.4cm x 5cm). The overall length is 12.5 inches (32cm) including the brass stake. There is a picture showing the owl in an 8 inch (20cm) flower pot for reference.
If you need more, I have them available, although each one is slightly different. I can send you individual pictures, just let me know. Also, other colors are available. Thanks.
