Quilted bag- part 1

This is the first part of a tutorial for a quilted bag. I haven't been able to get a photo of the finished thing, but heres one side.  

Equipment

1 fat quarter black

1 fat quarter pattern A

1 fat quarter pattern B

1 fat eighth patter C

1 metre lining fabric

Wadding, about 0.75 metres

Pins

Sewing machine

Tailors chalk

Black thread

How to

Draw 36 2 inch times 4 inch rectangles on the BLACK fabric with the tailors chalk. Cut them all out. 

Draw 18 4 inch times 4 inch sqares, 9 on fabric A and 9 on fabric B, then 16 2 inch times 2 inch squares

C. Cut them all out.

Arrange 9 of the big squares in a pattern going ABA, BAB, ABA

Pin a black rectangle and the first square RS together.

Sew them together with 1/4 inch seam allowance.

Continue adding rectangles and squares until you get a strip looking like this.

Take a black rectangle and small square- pattern C- and sew them together, RS together.

Keep attaching rectangles and squares until you get a strip like this.

Time to press all your seams! Lay them out like this on your ironing board, and flip over the leftmost one.

Press all the seams so they face towards you.

Press on top to smooth out any wrinkles.

Take the next strip, and press the seams so they face away from you. Press on top as well. Continue like this, pressing first towards, then away from you.

Pin your first 2 strips RS together.

Sew along the seam, with a 1/4 inch seam allowance.

Continue to sew the strips together, and iron the seams. For the other half of the bag, do the same as above, but place the 4 inch squares BAB, ABA, BAB.
