I first must give credit to hoax2 for thier Custom Sigils DIY mod, which is what prompted me to make this mod for skyrim.

Custom Sigils DIY

This is a very simple mod that is meant to be used by people that would like to put a custom banner into the game but don't want to play around with the CK and do it themselves. This mod puts a copy of one of the generic banners from skyrim in your data folder that can be edited and customized without changing any of the existing banners in the game.

Instructions:

1) Install this mod using NMM

2) Use your mad photoshop skillz to edit this file

• ...\Data\textures\clutter\customsigil\customsigilbanner.dds
  

3) Travel to the Riverwood Trade Post and view your new banner

• You will find it by the stairs hanging on the wall
  

To copy or move the banner you will need a  program like Jaxonz Positioner.

Future Plans:

These are things I would like to do , but due to lack of time they probably won't happen.

• Make the banner craftable
• Have it added to each house you purchase automatically
• An Option to make it through the Hearthfire house building system
