I made this bag for my best friends birthday, it has a zippered pocket in the back, a front pocket and a divider in the main compartment with a pocket (which is edged with piping covered in the outer fabric )
The outer fabric is a type of paisley-ish cord, it closes with a magnetic closure, and has D rings on either side to make the strap more comfortable (she often wears her bags diagonally across her) and I used ready made webbing because the cord had a bit of stretch to it and I figured it'd be more difficulty than it was worth
And this is a photo of the lining
I folded the front pocket and pressed it in place to make it so there wasn't a seam on it, I thought that it looked better that way. The entirety of the paisley fabric is interfaced with a medium weight interfacing, the divider is also interfaced, and then sewed inside out so there were fewer seams on show.
The fabric was about £3.90 for a metre, I've still got some left from that though, the pink was an old pillowcase (lovely soft cotton though) the webbing was about 0.30-0.50 pence per metre and I got 1.5 (but only used probably 1-1.2, can't remember)
I didn't use a pattern, I just sketched what I wanted and winged it.
Thanks for looking
