Blocks can roughly be placed into three broad categories as per their applications: primary motif blocks, border blocks, artistic or souvenir blocks.
Primary motif blocks are used for most of the fabric and get repeated over the cloth's length and breadth. Border blocks are thinner blocks that are used only on the edges of the fabrics for printing borders. Since both of these are repeatedly printed, their design is done to allow for repeats without overlap. On the other hand, souvenir or Artistic blocks are meant only for display or small prints and hence are usually not repeatable blocks.
