It's relatively simple, use these walls only to build a shell of your build. Use every wall, however you want. You can make them into halfwalls or spandrals if you want, but i challenge you not to if you want an extra hard version. <3 Put the pieces together, spin them around, place them however you want. Build whatever you want. Piece together THESE LINES ONLY. Don't add any other walls of any kind. Add porches, whatever else you want! Use #autyylines #trymesyd #shellchallenge #funshell
