The idea for the S2 bag has been mulling around in my head for a while. It's a very simple bag with one strap that crosses the bag (front to back). It's functional and easy to make and can be sewn up quickly. So here it is.
What you'll need:
Front and back panels: 13" x 14", cut 2 of main fabric (interfaced) and cut 2 of lining
Bottom: 13" x 4", cut 1 of main fabric (interfaced) and cut 1 of lining
Sides: 14" x 4", cut 2 of main fabric (interfaced) and cut 2 of lining
Tabs: 2.5" x 4", cut 4 of main fabric
Strap: 4" x 36", cut 1 of main fabric (interfaced)
2 "O" rings or "D" rings with a center opening of at least 1".
Magnetic snap and scrap of interfacing (for optional snap closure)
All seam allowances are 1/2".
Start by marking the wrong side of the bottom piece with dots 1/2" in from the corners in each direction. Do this for all four corners.
Pin the bottom to one of the front pieces (right sides together). Sew between the points you marked on the bottom.
Repeat on the other side of the bottom.
Mark the wrong side of the two side pieces with dots 1/2" in from the corners on the bottom.
Attach the side piece to the short edge of the bottom (right sides together) and sew between the dots.
Trim the corners of the bottom at a 45 degree angle.
Turn the side and pin to the front edge of the bag (right sides together) like this:
Sew along the edge (starting at the dot on the bottom) all the way up the side. Repeat for the other three sides.
Place this aside and repeat for the lining leaving a 4" opening in the bottom for turning.
If you want to add a magnetic closure, iron a small square of interfacing to the top, center of the lining (on the wrong side) and attach the magnetic closure per manufacturers instructions approximately 1.5" from the top (in the center).
Now we'll add the "O" rings. Take your tabs and place them right sides together. Sew on each long side to create a tube. (Shown on the left of the photo.) Turn right side out. Iron flat. (Shown on the right of the photo.)
Fold tabs in half and place an "O" ring on each tab.
Pin in place 2" in from side seam on the front of the bag (facing down toward the bottom of the bag).
Pin the other tab on the opposite face, 2" in from the opposite side seam.
Baste tabs onto the front and back of the bag.
With right sides together, pin the lining inside the outer bag like this.
Sew around the top of the bag. Turn it inside out.
Iron the top edge flat and baste around the top edge of the bag close to the edge.
Fold the handle in half, lengthwise, wrong sides together.
Open it up and fold both outer edges to the center fold line and iron again.
Fold in half again at original fold line and iron.
Sew down the side of the handle with a 1/8" seam. Repeat sew line on the other side for symmetry.
To attach the handle simply fold handle a couple of inches from the bottom and put it around the "O" ring. Fold the raw edge under again a little bit. Sew in place. Repeat for the other side making sure the strap isn't twisted.
Stitch up your turning hole on the inside of the bag (by hand) and you're done!
Finished bag measures: 13" h x 12" w x 3" d
