Because wire gets flimsier the longer you cut it, this method is best used for smaller arches.
Add a thin layer of colored sand or pebbles to your bucket. This will hide the plain sand or pebbles. Wrap bricks or cinderblocks in paper that matches your balloons. You can also paint them to match the base of your balloon arch.
Use a regular pump for this method, not a helium tank. You don’t have to use a balloon pump for this, but your lungs may get tired after a while.
Alternatively, you can tie the balloons together in a cross shape with some string.
You can also secure the balloons to the wire with string or colorful ribbon.
You can use all the same color or you can alternate colors. Stagger the balloons. Let the balloons in row two rest in the cracks between the balloons in row one. [6] X Research source
If you can’t find any fishing line, use white string instead. You can also use balloon ribbon that matches your color scheme. If you are making a large balloon arch, tie the string to a bucket handle instead. Fill the bucket with sand, gravel or pebbles. You can also tie string to a cinderblock if you are making a large balloon arch.
You can buy a helium tank from a party supply store or an arts and crafts store. Some places will also allow you to rent them instead.
If you used a cinderblock as your anchor, you will need to leave enough string to feed it through the holes on the block and tie it off.
Cover cinderblocks with wrapping paper. Paint the bucket with spray paint or acrylic paint. Fill the top layer of your bucket with colored sand or gravel. Tuck flowers into the bucket or cinderblock.
The arch does not have to be perfectly symmetrical. Try a warped arch for a more organic design.
Do not use a helium tank for this. You can blow the balloons up with your mouth, but your lungs may get tired.
You can find glue dots in the scrapbooking section or an arts and crafts store. They are dots of glue that come on a strip. Peel them off one at a time as you use them.
Secure the flowers to the chicken wire with glue dots or string. [16] X Research source Make sure that the flowers don’t have any thorns. If they do, cut them off with a crafting blade.
