As you can guess, this purse weighs quite a bit due to the heavy glass beads and wire. So if you want to make a lighter one, use different beads.
Hint: I recommend working with metal needles in the size to suit the wire and beads. Also, string the beads on to the wire before you start knitting. Work in a warm environment of at least 80 degrees or higher. This helps the wire be more pliable and avoid breakage. It can be a challenging moment to recover from snapping the wire in the middle of a row.
There are some fabulous books out there on knitting with wire, I have added a few links below but you can always check it out for yourself at your local craft store.
