This steamboat cardboard costume came about for a school project. The assignment was to construct a costume made of recycled materials. The point of this project was for students to practice roles of engineers and designers to make a product, thus, creating the flat pack costume design concept.

The job that the class took on was developing a line of costumes made from recycled cardboard. This cardboard then had to be able to slot together for assembly and taken apart for storage purposes. The costume would be ideal for people who wanted to make an easy costume while not spending much money for children to use under minimal supervision.

Design Brief:
I had to design and create a marine themed costume, made completely out of recycled cardboard using slotted construction with a flat pack costume design.

Specifications:
1. Middle school aged child must be able to wear this costume
2. Marine themed
3. Flat pack, slotted construction

Limits:
1. 100% cardboard, no tape, no glue, no permanent fasteners
2. Should be able to wear as Halloween costume or play costume

2. Cut outlined form of side 1 (S1) with utility knife (T2) on cutting mat (T1).

Step 3: Side 1 (continued)

3. Measure with ruler (T3), outline with pencil (T4), and cut slots of side 1 (S1) with utility knife (T2) on cutting mat (T1).
Slots- 6 total, 3 per side, 4 in. from bottom edge, 4 in. tall, ½ in. wide, 1 in. from outside edge, 2 in. apart

Step 4: Side 2 (S2), Right Side

1. Measure side 2 (S2) with ruler (T3) and outline with pencil (T4) the appropriate lengths. Copy lengths and widths of side 1 (P1) from step 1.

Step 5: Side 2 (continued)

2. Cut outlined form of side 2 (S2) with utility knife (T2) on cutting mat (T1).

Step 6: Side 2 (continued)

3. Measure and cut slots and tabs of side 2 (S2) with utility knife (T2) on cutting mat (T1).
For slots, copy side 1 (P1) on left side of cardboard. For tabs- refer to picture and repeat for each tab (3 total).

Step 7: Back (S3)

1. Measure back (S3) with ruler (T3) and outline with pencil (T4) the appropriate lengths.
Width- 2 ½ ft wide, 2 ft tall, for tabs, refer to picture with tabs in step 6 for both sides.

Step 8: Back (continued)

2. Cut outlined form of back (S3) with utility knife (T2) on cutting mat (T1).

Step 9: Assembling, (P1) and (P2)

1. Insert tabs of side 2 (P2) into slots of side 1 (P1).

Step 10: Assembling, (P1) and (P3)

2. Insert left set of tabs on back (P3) into slots of side 1 (P1).

Step 11: Assembling, (P2) and (P3)

3. Insert right set of tabs on back (P3) into slots of side 2 (P2).

Step 12: Final Product

Here's what the final costume should look like.

This product is constructed with medium/regular size measurements.
If sizes are preferred to be changed for different sized children, multiply original measurements by the following:

x-small: .6
small: .8
medium: don't change
large: 1.1

*painting is optional, however, be sure to paint both sides equally or cardboard will warp
