ATMOSPHERE
STEP 1
SELECT 9 SHEETS OF TISSUE PAPER. GLUE 4 OF THEM SIDE BY SIDE TO FORM THE SIDES OF YOUR BALLOON. (SEE PICTURE # 1)
STEP 2
With the remaining 5 sheets, make five squares (see picture 2)
STEP 3
Glue one of the five squares to the top of one of the sides. (see picture 3.)
STEP 4 With the remaining 4 squares, Cut 4 funnel-shaped pieces by Cutting a right triangle from Both sides of the squares withA base of approximately 6 to 8 inches. (see picture 4)
Step 5Glue the four funnel-shapedPieces to the bottom of each side.(See picture 5)

LAST STEPS
BEND THE WIRE INTO A CIRCLE ABOUT 6 INCHES IN DIAMETER, THEN GATHER THE BOTTOM OF THE BALLOON AROUND THE WIRE AND GLUE IT. (THIS MAKES LOTS MORE WRINKLES, LIKE A SLEEVE AROUND AN ELASTIC BAND.) (SEE PICS)
