Cut your frame wires an equal length. Collect your newly cut wires together. Draw a line to mark the middle of your bundled wire. Cut your first piece of binding wire. Bind your six-wire bundle at its middle mark. Mark the next binding sites for your six-wire frame bundle. Remove the tape from the ends of the wire bundle.
Take your 20-gauge square soft wire and clip six pieces eight inches (20 cm) long free. For centerpieces that are bulky or larger, you might need to measure out more wire. The central frame of your wire wrap should be:  Long enough to warp around the perimeter of your centerpiece. Thick enough to hold your centerpiece. Heavy/bulky centerpieces might require you to use more than six piece of wire. Line up the wires and draw them tightly together, making sure each is parallel to the others. Then should use your tape to bind the ends. This will keep your bundle in shape while you work with the wire. Depending on the contour of your centerpiece, you may find a rounded wire frame works best. In this example, the wire frame has been flattened to better contain the polished bead centerpiece. Lay out your bundled wire flat on your work space and, with your ruler, find the center of the bundle. Now, with your felt-tip pen, you should mark this point. This wire will be used to decoratively wrap around the middle mark you have just made on your bundle. Use your wire cutters to snip free a five inch (13 cm) piece of 22-gauge half-round hard wire. Use your flat-nosed pliers to grasp the piece of 22-gauge wire you cut free, then bend the wire around the bundle. After each winding, pull the wire tight while holding it against your bundle with your free hand. The bundle should be wrapped so there are no gaps in its twinnings, and should be equal length on both sides of your middle mark.  Grasping your wire close to its end with your pliers can make shaping it easier. After you finish your bundling, your middle mark should not be visible. This bundle will eventually make up the bottom of your wrap. The width of the finished binding should be approximately ¼" (6 mm) for a 12-carat stone, like the one used in this example. Use your ruler and felt tip marker to draw a line a ¼" (6 mm) from each edge of your center binding. Then make another mark a ¼" (6 mm) outward from each of your previous marks. These double marks on either side of your middle binding define the width of your next bindings. Now that you've got your middle binding in place and your lines drawn on each piece your six-wire bundle, you can remove your tape, as it is no longer needed to keep your bundle collected together.
