Introduction: Cardboard Loligo Vulgaris (Squid) Costume

     The costume design for this squid costume was for a school project. The assignment was to build an  efficient marine themed costume. Before actually getting to the final copy, many changes needed to be made to the original design, so that the squid costume was comfortable and safe.
 
Design Brief:
      The task was to develop a squid costume out of recycled cardboard. The cardboard is used so the pieces can slot together easily for middle school aged children for Halloween, plays, etc.

Specifications:
     The squid costume must be safe for the one wearing it, such as being comfortable and being able to see easily. The costume also needs to have a professional appearance.

Limitations:
     The squid costume needs to be made entirely out of cardboard
