Patches
From LittleBigPlanet Wiki
Patches are areas on the LittleBigPlanet and are the user created levels. Unlike levels in traditional games, patches in LittleBigPlanet can be freely edited by the players during play, without needing a seperate level editor.
The interface for editing the level appears above the player's sackboy in a bubble as though the sackboy is thinking or discussing what to do next. Once an action has been selected, the sackman produces a coloured thread which he wields as the player positions and manipulates an object. The interface is a different colour for each player, and multiple players can be manipulating the level at any time.
In order to create things within patches, players need to collect raw material. In the GDC Demonstration, this raw material was sponge, so it could be that this material is the stuffing of which the sackboys are made, and that they weave patches from their own substance.
