Try starting with a great invite. There are lots of options for buying minion invites online or you could make your own:
Take yellow cardstock and fold it in half, then trim to 5 1/2” long by 4 1/4” wide. Then, round all four corners of the card (with the card folded) with scissors to make an oval shape: the minion’s body. Next, use a half-inch circle punch to punch the eye shape from black paper. Or, just free-cut a circle. The edges will be covered in glitter and won’t show.
Next, trace the shape of the yellow minion body onto a piece of blue cardstock with a pencil. Cut out the blue shape, and then draw the minion’s overalls onto the bottom half of the blue shape in with a pencil. Cut out and glue the overalls to the bottom half of the card with a glue stick. Adhere large wiggle eyes in the center of each black circle. Add a line of white glue around the edge of each black circle and sprinkle with silver glitter.
While waiting for the glue to dry, draw in overall buttons on the minion’s clothing with a black marker. Don’t forget the other details, such as hair and a smile! When the eyes have dried, glue to the minion body and cut two thin strips of black cardstock for goggle earpieces and add to your minion. Write the party info on the inside page of your card.
