Sewing the back piece to gusset

Sewing the back piece is exactly like sewing on the front piece. The only difference is that you have to measure where the gusset should start as you don't have a fixed starting point. If your front piece is 31 cm high then your starting point should be 31 cm from the bottom of the back piece.

If your front piece is 31 cm high then the gusset should start 31 cm from the bottom of the back piece.

 After the contact cement has dried bond the gusset and back piece together just like with the front piece.

 As you can see the gusset and the remaining of the bottom back

 Here you can see it a bit more clearly.

 Make a small fold and bond it where my finger is.

 Press it down. By doing this you compress the gusset a tiny bit which will make sure that the two pieces will have the same length. Do this as many times as needed in both sides.

 You can form the corners a bit with a former tool.

 All glued up.
