Now sew the top trim (Piece "C") to each main body (Piece "A") RST 1/4" seam , press the seams open.
Oringinally, I sewed the front and back RST and boxed the bottom 2 ", but didn't like that so, the seam ripper made an appearance and I decided to install the gussets.
Sew the side Gussets RST to the Bottom Gusset matching the 4" ends. Press the seams open.
The construction of the lining is basically the same. First do the pocket pieces "B" ( I did not put any zippers in these, instead I put credit card sized slip pockets on them. Add zippered pockets to the main body pieces "A" . Sew pocket pieces onto the lining main body pieces "A". you do not put the top trim pieces on at this time. After cutting off the top 2" of the lining side gusset pieces--they should be 10" high matching the main body piece , sew the lining side gusset pieces to the lining bottom gusset matching up the 4" sides (same as the outer shell). Again, pin or clip the gusset unit to the lining front matching up the corners and tops (it should match up this time) Sew slowly and carefully with a 1/2" seam.Corners will be difficult. Attach the lining back to the lining gussets again taking it slow.
Almost done !!!
Next post will be putting the outer shell together with the lining and the recessed zipper.
Happy Sewing !
