A lot of other skills are variations of the eye-pin so practice this until you can form them quickly and uniformly.
What You Need:
Practice Wire ( 18 - 20 gauge is good for practice)
Round Nose Pliers
Start by cutting the wire flush with your flush cutters, making sure the flush side is on the end of the wire. Next grasp the end of the wire with the round nose pliers. Make sure the end of the wire if flush with the barrel of the pliers. If not, you will end up with an oblong loop, not a round one.
The size of the loop is determined by how far down the barrel of the pliers you grasp the wire. Start to roll the wire away from you, until a complete loop is formed. If you can’t complete this in one motion, it’s ok to reposition the pliers into a more comfortable position.
Once the complete loop is formed it will be round but it won’t be centered on the rest of the wire. To accomplish this, place the upper barrel of the pliers in the loop and rest the lower barrel against the rest of the wire. Using the lower barrel as the pivot point, rotate the loop until it’s centered on the wire. This will form a slight bend at the base of the loop.
