A requirement of my technology class we had to create a marine-themed costume only using cardboard. No glue, no tape or adhesive of any kind. Therefore we had to research different ways that we could put these costumes together.

Design Brief: Create an oyster costume using cardboard and slotted construction.

Specifications:-Costume must resemble an oyster
   -Costume must stay together
   -Costume must be made of cardboard

Limitations:-Materials
   1. Cardboard
   -Material strength
   -Construction methods
   1. Slotted Construction

Step 1: Materials and Tool List

Materials:
   S1. CARDBOARD- 3 4'x4' pieces

Tool and Equipment List:
   T1. CUTTING MAT-To prevent damage to floor/surface
   T2. UTILITY KNIFE-To cut out pieces of cardboard
   T3. RULER-To make straight lines and measure out correct lengths of pieces
   T4. PENCIL-To draw out lines that you will cut along

Step 2: Part List

Parts:
   P1. Front Panel, Quantity: 1
