Yes , you would , but as it only a pole ( as far as i'm aware ) or a tripod , it shouldn't make a difference should it? If you extend a cone shape , the angle remain the same while the base size increases?
Or am i missing something?
No that's right, but you wouldn't be able to just button in the extra sections, you would need to get the sewing machine out and extend all around the bottom too. Perhaps that's what you have in mind though?
