What I particularly liked about the original bag was the kind of wrap around handle, made out a rectangle of unlined fabric. A soft fabric like a scarf would be ideal.
I tackled the body of the bag as two rectangles ( 52cm width, 64 cm length ), with rectangles (5.5cm width, 11 cms length) cut out in the "Jordy" fashion.
The fabric frays so much, I thought I would line it with interfacing, but it didnt stick very well at all, GRUMBLE!,
so in frustration, I sewed bands of thin black ribbon across the outside fabric to help hold it in place.
Now I like the look, so its all good. I figured sewing the pockets in would help hold the interfacing to the lining.
Then I thought the bag would look better with a pleated top. 4 peices 10cm by 37 cm.
I hate gathering so just pinned little pleats till the main fabric was the same length as the bands. 7 pleats held in place with pins was just right, and I sewed carefully and was able to sew straight over the pins. Yah!
sew bands to either ends, You can see the rectangles cut out of the body of the bag in this pic
you should have pieces that look like this
Handle is one piece 105cm long by 25 cm across. I zigzaged a hem down both sides,( at this point if you want a reversable bag, you would need double the fabric and sew the handle right sides togeter as a tube, then turn the right way).
Big pocket is a rectangle 48cm height by 27cm width, folded in half, right sides together, stitched most of the way around, turned in the right way, ironed flat and topstitched closed. Sewn to the bag lining where desired. finished pocket will be about 23 cm height, 25 cm width.
Small pocket is 34cm height by 13cm width, sewn as above.(these sizes where dictated by the fabric I had left over)
With right sides together, sew each of the main pieces together down their sides
because this fabric is so prone to fraying, I stitched twice and zigzaged also
Then fold the bottom openings across and stitch closed. I am not pulling the bag through the base like a "Jordy"
Turn the exterior bag in the right way
Wrap the handle around the bag, right side to right side and tuck into the lining, right side to right side ( its late, oh how I hope that makes sense!)
Pin all layers together around the top and stitch, leaving an opening a bit bigger than your hand.
Pull the bag inside through this opening.
Topstitch around top of bag, folding the opening edges in, ( you wont see them trust me)
your bag is now ready to photograph!
(phew that took the longest time! night!)
