Materials: a balloon; an air pump; sewing thread and scissors.
Inflate a balloon leaving a five—inch flat tail (Pic 1).
Twist the first soft two—inch bubble (Pic 2).
Lock both ends of the first bubble in one lock twist (Pic 3). This step is marked with arrows between points A and B on the scheme.
Twist the second four—inch bubble (Pic 4).
Twist the third soft one—inch bubble (Pic 5).
Lock both ends of the third bubble in one lock twist (Pic 6). This step is marked with arrows between points C and D on the scheme.
Twist the fourth ten—inch bubble (Pic 7).
Lock both ends of the fourth bubble in one lock twist (Pic 8). This step is marked with arrows between points E and D on the scheme. The rest of the balloon is the fifth bubble.
Cut off the fifth bubble and tie off the end. Congratulations, you have made the digit 6 or the digit 9 if you turn upside down the digit 6 (Pic 9 and 10).
Choose appropriate color sewing thread to fix the sculpture in the shape of the digit 6 and to attach it to other letters or digits (Pic 11 and 12). After you made and connected all digits and letters in words you can attach the signs you made to a wall with a sticky tape. Have fun and happy twisting :)
