Here are some ideas on how to decorate your windows:
Wreaths- hanging a wreath “(or several) by a ribbon in your window is a great way to affordably add some great texture and color to your room.
Ornaments hung by a ribbon. Just like the wreaths ornaments can add a fun pop of sparkle into a room.
Hanging Pine Cones- just like the wreath and the ornaments, pine cones can be a fun addition to your windows.
Using a frosted window spray paint also makes for a fun window treatment in addition to the hanging ornaments.
