Let's see how to attach jump rings together or to a charm, working with ImpressArt products.
What you need:
Step 1
Use the tips of two round-nose pliers to grasp the ends of the jump ring, keeping the openings facing towards the pliers.

Step 2
To open the jump ring, twist the ends laterally in opposite directions.
NOTE - Do not open the two ends of the jump ring outward to avoid distorting its circular shape and weakening the metal.
Step 3
While firmly holding the jump ring with one of the pliers, slide it into the hole of the flat wire.
Step 4
To close the jump ring, applying some tension, twist the ends laterally until they touch each other.
