The purpose of this costume is for a school project. The main idea is to create a marine themed costume using only cardboard and flat-pack construction. The costumes are either going to be worn for Halloween or a school play. The costumes are for middle school aged children. The Octopus that I designed is from a line of costumes related to the movie Finding Nemo. The group decided that these costumes would be for a play.
Design Brief: Design and develop a marine themed costume using only cardboard and slotted construction.
- double-ply or single-ply cardboard

Using a ruler (T3) measure 2'6" x 3 FT rectangle onto a piece of cardboard (S1)
Using a pencil (T4) draw the measurements onto the cardboard (S1)
Cut out the cardboard (S1) using a utility knife (T2) on top of a cutting mat
Measure with a ruler (T3) 3" up from the bottom
On top of the cutting mat (T1) make four 5" cuts using utility knife (T2) evenly placed on the cardboard (S1)
Measure with ruler (T3) 3" in from the edge, on both sides
Using utility knife (T2) on top of cutting mat (T1) cut up half way on both sides and cut off 4 1/2" off the bottom
At the top, measure with ruler (T3) 3" down and 5" across
Cut in a semi circle using a utility knife (T2) on top of a cutting mat (T1)
If needed, cut arm holes using utility knife (T2) on top of cutting mat (T1)
Take the second piece of big cardboard:
Follow steps 1-6 from previous slides
Using utility knife (T2) on top of cutting mat (T1) cut down half way and cut away 4 1/2" from the bottom
Take smaller piece of cardboard:
Using ruler (T3) measure and draw with a pencil (T4) 6" x 1' rectangle onto cardboard (S2)
Repeat this step eight times
Using pencil (T4) draw tentacle shape on cardboard (S2)
Cut out shape with scissors
Score along flap and fold back
- 8 tentacles

- 1 body piece (back)
Insert each flap of the body (P2) into each flap of the body (P3) that was cut up half way and down half way into each other. Fold inside the body pieces so that the flaps are not showing
Insert each tentacle (P1) itno the slits on the body piece
