You will need:
A pair of scissors
Needle and thread
A circular objet (diameter approx 5 inches)
Using the circular object as a guide; draw two circles on the denim cloth. Cut out the two circles leaving an allowance for sewing.
Measure the diameter of the circles, multiply this by 3.142 to get the length of the rectangular piece. Use 10 inches for the width of the rectangular piece.
Sew circular pieces on either length of the rectangular piece.
Sew in a zip at the opening of your bag
Cut out two rectangles measuring approx 16x2.5 inches. Fold each piece right side in, sew along the length and turn them right side out. These will be your straps.
Attach the straps to the sides of your bag.
Pin the studs on your bag in any way you find looks best. I pinned my studs on the straps and along the sides of the bag.
TIP. Studs concentrated in a particular spot look better than when they are scattered all over with wide gaps.
Use the same circular object to draw circles on a cereal box or hard plastic. Cut out the circles and put them inside your bag
You can also cut out a rectangular and place it inside your bag to give it shape.
