What you will Need Bumalong Bag

Step 1: Cut your Fabrics

Cut three 10″ x 8″ pieces of exterior fabric, three 10″ x 8″ pieces of lining fabric and three 10″ x 8″ pieces of interfacing.  Cut four 5″ x 5″ pieces of lining fabric or outer fabric for pockets and one 3″ x WOF (Width of Fabric) piece of exterior fabric.  Fuse the interfacing to all three of the exterior pieces.  Measure 3 1/2″ down from the top of the short edge of one of the exterior pieces and lining pieces and cut across to make two pieces.

Step 2: Add the zipper

Place the longer of the two pieces right side up on your table.  Lay the zipper on the edge of the fabric right side down.  Lay the corresponding lining piece right side down on the zipper to make a zipper sandwich. Sew the zipper to the fabric using a zipper foot.  fold back the fabric to reveal the zipper and press.  Top stitch along the zipper for a more professional look.  Repeat with the other side of the zipper using the smaller pieces of fabric.

Step 3:  Create the Outer Bag

Take another piece of the exterior fabric and place it so that the right side is facing the wrong side of the piece you just placed the zipper.  You could also use a lining piece if you like because this will serve as the lining for your zippered pocket.  Next, place the other exterior piece right sides together with the zippered piece.  You should have three layers of fabric.  Trim all the pieces to the same length. Sew all three pieces together around the two long sides and the bottom short side using a 1/4″ seam allowance.  Turn the pouch so that two right sides are facing out including the zippered side.

Step 4:  Add the pockets

Take the four small lining pieces and sew two of them together leaving a small hole at the bottom to turn them.  Clip the corners and turn them right sides out and press.  Sew a line across the top of one of the long sides for a finished look. Repeat with the second set of small lining pieces.  Sew these pieces onto the right side of the larger lining pieces.  This will make the slip pockets for your bag.

Step 5: Add the magnetic snaps

Take to two lining pieces with the slip pockets and fuse a piece of Peltex or other heavyweight interfacing onto the wrong side of the lining where you want your snap to be.  I use the Peltex to shore up the fabric so that the magnetic snap will be stronger and last longer.  Insert the magnetic snap by simply taking the backing pieces where the two slits are and mark them.  Cut the slits using a seam ripper then insert the snap and the backing piece and fold over the prongs.  I measured 1 1/4″ down from the top and center for my snap.  Then sew the long sides and the bottom leaving an opening for turning.

Step 6: sew the strap

Next, make the strap.  Take the 3″ x WOF strip and fold it in half long ways and press.  Open it up then fold each side to the center and press then fold again to make a nice strong strap. Top stitch  along both long edges for a finished edge.  Attach the ends of the strap to the exterior pouch right sides together at the side seams and pin. Insert the right side of the outer bag into the right side of the lining bag pushing the strap inside. Stitch around the top edge of the bag.

Step 7: Finish the bag

Push the exterior bag and strap through the gap you left in the lining.  You will then have one long bag that is half outer fabric and half lining fabric.  Sew the opening closed using ladder stitch then push the lining into the outer bag.  You will now have the right sides of the outer bag facing you with the strap on the outside and the right sides of the lining fabric and the magnetic snaps facing inside the bag.  Press.  Top stitch around the top of the outside of the bag for a finished look and you have completed this Bumalong Bag tutorial.
