I wish I had better photos to illustrate my point here, but...
Here is a picture of two table lamps, made from custom frames that I ordered in:
Which one do you think was made from special, expensive, adhesive backed card specifically designed for making lampshades?
Which one was made using plain white polyproylene?
It's hard to see here (taking photos of lighting is haaaard), but the one on the left glows a hideous orange colour, no matter what the fabric or bulb is. The one on the right is perfect. You'd be forgiven for thinking the perfect one was made with the fancy card. But oh no - that would be the ugly orange one.
I think I've had it up to my ears with H***works now. Not only are they badly located and the staff are often rude, but they also sell an expensive and inferior product. I spent $70 on this stuff only to find it was really crap.
Lesson learnt - stick to what you know works well, even if it is a bit more fiddly.
That all said, I'm really happy with how the good one turned out. Exactly how I pictured it in my mind. I'm going to make a few more to sell ... somewhere.
