This is all about wire ends needing to be hidden and secured.
You must secure them to avoid scratchiness and hide them for a clean design.
My advice: work with as few wire ends as possible!
If your project requires a large amount of wire 3 feet, 6 feet, or even 12 feet coiling and wrapping that length can be tricky.
Over the years, I developed a method I think you'll love.
Wrap the wire into a spool, like in this image, leaving about a foot or foot and a half free to work with.
Make the rest into a spool on your palm or around something round, like a spray can.
Use this spool to weave and coil it makes the process easier, faster, and helps you avoid starting and ending multiple shorter wires.
