Pros : Odyssey's shade construction system is the easiest I've found (I also do candlemaking so using wax is not a problem). While this pattern is not a Tiffany reproduction it is definitely a well designed pattern in the vein of Tiffany Studio's finest work.
Cons : No cons really, just be aware that there are a lot of pieces to this pattern (1,125 of them) and take care when choosing glass. Not for the novice.
Other Thoughts : Realistic colors for the flowers work best, especially rusts or yellows, but also the right shades of purple can be quite beautiful too.
