this is my minion, step one, head out to your local hardware store, and pick up some materials
two blue recyclable trash cans(i found them at lowes for $11,)
some masking tape,
news paper,
black pipe cleaners,
sunburst yellow spray paint,
2" plastic chromed plumbing plates,
an old duffle bag shoulder strap,
4, 1"x1/4 thread carrage bolts,
4, 1/4" washers
4 1/4" wing nuts
white cardboard, about a 4" x 6" piece
googly eyes

tools needed:
hot glue gun
drill and 1/4" drill bit
razor knife

Step 1: Prep Work, Body and Paint

the trash cans will fit snug together if you cut the top off of one of them just above the handles, then putting one on top of the other with the top one inverted. so that the bottom of the first can sits on the ground as normal and the bottom of the second can is now the top of the head of the body.

with a fine dark blue marker draw an outline of the coveralls that your minion wears, this will be the separation of yellow and blue,

mask off all of the blue clothing area, and spray paint everything else yellow and let dry

Step 2: I See You

take the 2" plumbing plates, cut out white cardboard to fit behind plates, glue cardboard to back of plates, then glue googly eyes to white cardboard, when dry glue eyes together in the center and hot glue eyes onto face, about 5" from top of head.

and about 5" under eyes cut out a mouth with sharp razor knife, be careful and do not cut toward yourself.

hot glue your duffle bag strap around the head to look like glasses straps

Step 3: Here a Hair There a Hair

fold about a dozen black pipe cleaners in half, poke holes in top of head and insert folded pipe cleaners into holes and hot glue them in place, when cooled separate and style hair

Step 4: Its a Mouth Full

get a piece of cardboard about 3" larger than the mouth on all sides, hold the cardboard inside of the body and trace the mouth hole that you have cut out onto the cardboard, carefully cut out the cardboard mouth shape saving the outside template and discarding the inside piece. now you have a cardboard mouth. cut some teeth out of the foam sheets and glue them onto the cardboard, use construction paper and cut out a tongue, glue it to the back of the teeth, finally cut a large enough piece of black nylons to cover the entire cardboard from behind the teeth and tongue,

hot glue the whole mouth assembly inside the body facing out to finish the mouth

Step 5: Arm and Arm

cut out arm holes on both sides, here you can see how the top and bottom fit together

Step 6: Its Alive......

drill 4 holes through midsection of body where both pieces come together, 2 in front and 2 in back. put carriage bolts through holes, put washers on threads and finally wing nuts to hold it together. and cut out the very bottom to allow you to pull the minion over your head to wear

find or make a yellow long sleeve shirt and some black gloves and you are set. you will be looking through his mouth once you are inside through the nylons. no one can see in.

if you have a smart phone there are a number of apps that have sound boards to allow your minion to talk
