Hi, this is my first blog, it's how to make an oversized item frame!
So it's with maps, I think it only works on the first map you create, and I'm not sure if it works in survival mode, anyway, here's how to make it:
1. Take an ENTIRE stack of maps from the creative inventory (remember, you need to have no maps already created)
2.Start spamming the maps so they become multiple filled maps
3.Look for the map that's an empty map, but still has an arrow indicating where you are (the arrow won't move or even turn)
4.Place it on the item frame
5.The item frame will become bigger! (but you can't place more items in)

Have fun with this bug!
