Before you commit

LEGO Building

  • Display and storage space is the real constraint once you have a few builds.
  • Following instructions is easy; designing original creations is a steep step up.

Postcrossing

  • Postcards and international stamps are a small ongoing cost.
  • Mail is slow — there's a built-in waiting game.
  • It's gentle and social rather than skill-building.
