As always, it is important to read through the directions before beginning any project. "Why am I doing this now and/or this way?" will usually be answered or make sense in steps further on in the instructions.
WHAT IF I DON'T WANT TO SOLDER?
This bracelet series is designed around getting more comfortable with soldering using inexpensive materials. Many of the shapes that are attached with solder can also be attached with small rivets, so don't let lack of equipment and supplies for soldering stop you.
Some beautiful base metal bezel cups that would melt if soldered can be riveted in place. Place an open backed bezel on metal backing. Mark where to drill or punch holes for rivets. Remove the bezel. Cut the holes, insert the rivets and attach the bezel.
Think "outside the box" a bit and you will end up with beautiful bracelet links to be proud of.
