Hi Deborah, that depends on the situation and the items getting soldered together. Smaller items can typically be soldered together with out a vent hole, but can explode if you go back and solder something else on. The earrings in this project have a slight opening on one end so there is a built in vent. The notches are used to hold the binding wire in place as your soldering. I hope this is of some help.

Great earrings! I understand if you solder two pieces together that do not have an escape for the air it can explode. Do these have an area that does not meet when soldering? Or is the notch he mentioned for that purpose? Thanks!
