I had the urge to crochet something small and thought some mini granny squares would make a cool bracelet. Before I knew it, I had made a few of these, so I devised a simple fastener that would allow me to switch them out with ease.
Step 1: Materials
sock yarn or embroidery floss
crochet needle that matches your yarn
rivets that are taller than your leather
Step 2: Granny Squares
Crochet three granny squares. If you've never crocheted a granny square before, check out this instructable.
Step 3: Joining Squares
I opted to crochet another layer around the outside of the three squares and then use a row of single stitches to to join the middles.
There are plenty of other methods you could use, however, be sure you aren't adding too much length to the bracelet in the process. For example, if I used the join-as-you-go method at this point, it would add another four layers to the length with two more layers in between each square. Of course, if you have a larger wrist, you may want the added length.
Step 4: Fastener
Cut a small piece of leather that is the same height as your bracelet.
The width is determined by your wrist. Wrap the bracelet around your wrist and get a general idea of how wide the gap is between the ends. I used a rubber band to hold it for the picture. This may be helpful if you want to get a precise measurement, but remember that the bracelet will stretch.
The gap in my bracelet was closer to 1.5" but I cut my leather to about an 1" so it would stretch tightly.
Step 5: Rivets
Use straight pins to mark the placement of the holes in the end of the last granny square. With the three layers I created, there are four natural holes in the crochet. If you have more or less layers, you may have a different number.
Pull out the straight pins and you'll be able to see the small holes from the pins.
Use a leather punch to put holes on your marks large enough for your rivets.
Punch holes in the same place on the opposite side.
Apply your rivets. Remember, they need to be taller than your leather. I used some that just snapped on instead of needing to be hammered.
Step 6: Wear
Slip the holes at the end of the bracelet onto the rivets, wrap the bracelet around your wrist, and slip the other end on the the other set of rivets.
Step 7: Enjoy!
Now you can crochet a series of bracelets in any combination of colors and change them out whenever the mood strikes.
