HEDGEWORX
By Wagi

While there have been a number of excellent hedge sets created and release - Spanky, Jonnyears, MGP and others, belotto33 mentioned that he was still in need of a set with specific pieces.  I decided to give it a shot, and while I may not have met all his expectations, I hoped I came closer.
The set uses a matching ivy pattern, it includes straight, diagonal, curved and specialty walls in various sizes, piers in three sizes, spheres, spires, trees and a few other items.  The piers are designed to cover where two wall are at right angles, so that the dreaded 'texture flashing' doesn't occur.  Walls can be stacked.  There's around 25+ items.

The pieces and placements in this set are based off of Moby's Steel Jungle sets, and therefore he deserves the credit for the logistics of this set. I simply expanded on his ideas.

If the problem still is not resolved, please contact me with the contact information at the bottom of this readme.

This is my first cso set ever.
Author/Creator: jordy_rym

This is a versatile glass wallset, with framework to support.
The glass panes are recolourable, reversable and quarter-tile. There are many variations of slants and curves.  This set works well with many other quarter-tile sets.
There are 24 vertically straight glass panes, 46 slanted glass panes, 21 Flat Roof glass panes, and 50 types of frames, totalling 141 objects. All very compatible.

This set contains a formidable frameset.  Also work well as stand-alone supports;
The naming system and icon set have been carefully thought out to make the set as user friendly as possible with this large number of objects.  With a bit of practice you should be fine.
Install into StyleThemed as usual.
