Cut at least four 10 x 60-70mm strips of copper sheet and etch with patterns of your choice (See below).
To make an adjustable hat band, cut the leather to about 21".
Lay out pattern, including the Strap Tips, and use shears to trim copper or brass strips as necessary to fit pattern. File all edges and corners smooth.
Cut 3 pieces of 28-gauge wire, each approximately 6". Use this wire to make a "crown" for each spiral heart charm by wire-wrapping seed beads around each top loop. 5 size 13/0 seed beads fit nicely (one per wrap of wire), leaving just enough room for 2-3 end wraps. As you go, pull each loop tight with nylon jaw pliers and gently adjust the bead placement with the nylon jaw pliers. To finish, pull the wires around the back, twist them 5-6x with the pliers, flatten/hide along the back of the heart, and trim excess.
Use the cutting end of the Crafted Findings tool to punch a 1/16" hole in the center of each spiral heart.
Set a heart on the center of the hat band, and use an extra-fine point marker to mark the spot to punch. Punch 1/16" hole in the center of the hat band.
Punch a 1/16" hole in a vinyl heishi bead. The vinyl heishi beads will be washers to hold the back of each rivet secure in the leather. Use them on the back side of the leather for EVERY Crafted Findings rivet on this piece.
Select a mid-length rivet from the assortment. Run it through the heart, leather and a heishi. It should stick out 1-2mm. If not, select a different length. Set the rivet.
Place a wing on each side. Note that the right-side wing domes the wrong way for the hat band. Use finger pressure and the flat nylon-jaw pliers to gently/slightly dome it the proper direction for the hat band.
Mark a dot near the tip of each wing but not too close to the tip or edges. Punch a hole here to rivet, but if you punch too close to the edges, the charm will crack.
Set a pair of wings on the leather near the center heart, align carefully, and mark dots to punch. Punch one hole at a time, and set the 1st rivet before double-checking placement and punching the next hole for the next rivet. After setting both wings this way, double-check entire pattern again. You can trim and file a little off one of the metal strips if you make a little mistake along the way.
Use the widest part of the oval bracelet mandrel to gently bend each metal strip to about the same arc as a hat.
Carefully punch each hole and set each rivet, always using a washer/heishi on the back.
Use the other style rivets to attach the strap tip links to each end of the leather strip. These are designed for leather, so you don't need a washer. Why didn't we use these for the whole project? Because they are 2.5mm diameter, too thick for the sweet little wing and heart charms.
Place the Strap Tip Link on the end of the leather, mark hole to punch, set Leather Hole Punch to 2.5mm, and punch hole in leather. Run the bottom of the 2-part rivet set through the leather, and set it on a steel bench block; add the strap tip link and top half of the rivet. Place the Rivet Setter on top, and tap firmly a time or 2 with a brass hammer. Check the rivetto see if it is wiggly. If so, tap it again. Repeat on other end of hat band.
To make an adjustable hat band, add a series of heavy solid copper oval jump rings to these links. On one end, add 2 to 4 jump rings, and then the S clasp. On the other side, add 6 to 20 jump rings. Add a spiral heart charm to the last loop. Gently open one end of the S clasp just enough that it can go onto any of these oval loops, but won't open too easily.
