A very VERY simple resource pack that makes item frames invisible.
No fuss, no code, no wandering around, it just works. Go decorate!
To install, take the FrameAway.zip and place it into your resourcepack folder.
To activate, simply click options, then resource pack and enable it there. If you can't find your folder to put the zip file into, there's a button here that points you the way too.
If you ever think you need to see your frames again, just deactivate the resource pack. It's that easy!
