Make the shape
First of all, you need to make a frame on which all the balloons will be attached. You can choose to make one yourself from household items such as PVC pipes or plastic rods, but if you’re in the mood for something more professional, then balloon stores should probably be able to help you out.
Check the length
According to the length and height of your heart-shaped arch, you will determine how many balloons will be needed to cover the entire area. For good measure, add about four balloons per foot.
Fill the Balloons
It’s very important that all of your balloons line up similarly and are not varied in size by a large margin. So while filling them with helium, make sure to compare and contrast the sizes by using a cardboard template for accurate measurement, this will keep everything in check and ensure that the overall design does not look awkward.
Tie the Balloons
This is the most tricky and essential part. Balloons should be tied accordingly with their necks and then coupled together with a cluster, so that there is one on each side. Continue this step with all the balloons you have filled, but remember to observe caution, otherwise they could burst and send you reeling to the helium filler once more.
Attach the Balloons
Now that the clusters have been made, it’s time to attach them onto the frame. Twist the clusters at each end and carefully start from the bottom of the frame, continuing to attach balloons as you go. End this cycle after completely filling the frame.
Secure and add colour
With the majority of the Balloons attached to the frame, you can see to it that the frame itself does not fly away with so much helium on it. If there is a wall or nearby furniture, then you simply choose to tie it with that, but if there is no such option, then nailing it to the ground maybe your only hope of ensuring that the frame does not take to the skies. After you’re done with this, add a spot of colour, with red obviously being the most preferred choice.
