How to make large balloon sculpture base for 2 numbers

Tips: Do not put too much air in foil number balloons, it is much easier to glue balloons together if the surface is slightly soft. Apply multiple glue dots on the joint point to glue balloons together. Tear the balloon glue sheets into stripes to use.
Recommended tools: balloon pump, measuring tape

 

1. Blow up 16PCs 12inch balloons to similar sizes, tie knots. Suggest around 22cm. (place a ruler or measuring tape or an object next to the balloon when blowing)

2. Tie 2 of them together to make 8 pairs.

Pick the balloon colour you like to put together, blow them up to similar size, tie 2 balloons together to make a pair 

3. Pick 2 pairs, stack them on top of each other like a shape of cross, twist the joint to join them together to make one set, then level them. (Don't worry if they move, as long as they join together)

4. Repeat step 3, make four 12inch balloon sets.

 

 

5. Blow up 12PCs 5inch white balloons (suggest around 10cm), tie 2 of them together to make 6 pairs, repeat step 3, make three 5inch sets.

 

6. (You will need some space in this step) Open the ribbon, place it on a flat surface, then place first 12inch balloon set on top of the ribbon. 

7. Place a 5inch set on top of the 12inch set (rotate 45 degrees), pull the ribbon around the balloon gaps up and down several times to tie them together. 

 

8. As the picture shows, place 12inch set and 5inch set on top, one after each other, each time rotate 45 degrees and tie, until the base is stable, pull tight and tie a knot. Base is made.

 

9. Blow up the number balloons, if you have a name sticker stick it on. 

 

10. Place the number balloons on the top of the base, find the best position and stick them onto the base by using multiple glue dots until they are glued on securely. 

11. Glue other decorative foil balloons or 5inch balloons on to finish. 

 

 12. You can also make a 5-layer base by making 5-set of 12inch balloons(step 4) and 4-set of 5inch balloons(step 5), then glue all decorative balloons on the base.
