Balloon Arch 'String of Pearls'
- Step-by-Step Tutorial -

A floating balloon arch is perfect for creating a beautiful walk through decoration or for framing the head table at a wedding reception. 

Here we show you how to put together a classic 'String of Pearls' floating arch.

Before you start building the balloon arch, you need to know how long your line should be and how many balloons you are going to need. Click here for the formula.

What you need for a 'String of Pearls' Balloon Arch:

Special Tip:
The bases here are the same design as used for the balloon bouquet 'Simple & Elegant', just a bit bigger, roughly 9cm diameter.

Step 1: Attaching the Fishing Line to the Base 

How to make a balloon arch, step 1

Take one end of the nylon line, pass it through the hoop on one of your pre-prepared bases and tie it with two or three securing knots (fig. 1). 

Unroll as much of the line as you need, but don't cut it at this point, until you have all your balloons attached. Not only will it make the arch easier to handle, but you also eliminate the risk of winding up short on the length.

As the old carpenters saying goes: "You can always cut it off, but you can't put it back!"

Special Tip:
Unless you have an assistant to hold the other end of the line, you can stretch it out between two chairs and temporarily tie it off. This will save you wrestling with the line as you're attaching your balloons and give you a comfortable working height.

Step Two: Inflating the Balloons and Attaching them to the Line

Take the first of your balloons and inflate it with helium, keeping a firm grip around the neck (fig. 2). Check its size with your balloon sizer and inflate or deflate as needed (fig. 3).

Now comes the tricky part, knotting the balloon directly onto the line. If you've already looked at our tip how to tie a balloon knot, it's pretty much the same except that as you stretch out the neck the line should be running over the top of it (fig. 4).

And as you start tying, the knot will form around the line (fig. 5). Sure, it's a bit fiddly, but by the time you come to your last balloon you'll be doing it like a 'pro'!

Step Three: Adding the Remaining Balloons and Curling Ribbons to Your Balloon Arch

Position your first balloon on the nylon line about 10 to 15 cm above the base. If you wet the nylon line with your fingers, you'll find the balloon slides along very easily. 

Take about 1 m of your curling ribbon and tie it to the neck of the balloon, so that you are left with two equal lengths hanging from it (fig. 6). Now curl the ribbons, using the open blades of your scissors. We recommend doing this for each balloon as you go along, but you may prefer to wait until all the balloons are attached.

Inflate and attach your second balloon as explained in step two. Then position it so that it's just touching the first balloon (fig. 7).

Repeat steps two and three for all your remaining balloons. Your 'String of Pearls' arch is almost finished. All you need to do now is to cut the nylon line from the roll, leaving about a meter to play with and attach it to the second base with a temporary knot.

With your decoration in its final position, stand back and check that you're happy with the height and the spacing of the balloons. Make any adjustments, if necessary, and then finally tie your securing knots on the base.

Special Tip: 
There are many ways to add extra touches. In our example we crowned the archway with a red mylar heart to tie in with the theme of this decoration.
