    FULL TUTORIAL VIDEO

     

    1. Cut out the pattern pieces

    Cut out the paper pattern, then transfer the different pieces onto the leather, the lining (pigskin) and the Salpa reinforcement. Before cutting, carefully check the placement of the pieces on the leather.

    Cut out the pattern pieces

    Using a utility knife or scissors, cut the leather, lining, and Salpa following the lines.

    Note 1 : For piece P1, follow the black lines to cut the piece from the leather. Then follow the blue lines to cut the lining piece. On some sides, a 3 mm margin has been removed so that the lining does not protrude from the edges of the bag.

    Note 2 : For piece P2, proceed in the same way as for P1. First cut a rectangle from the lining following the blue line. Then cut the leather following the black lines (do not cut the ogival end immediately - dotted lines).

    Note 3 : For the two P9 pieces, fold the pieces in half and cut the corners at the fold to easily create the notches.

    2. Prepare the bag strap

    In this version, the strap is made from nylon webbing. Depending on the desired style, it is also possible to choose a cotton strap, a bag chain, a leather strap, or no strap at all. It is also entirely possible to make an adjustable shoulder strap with a sliding buckle.

    Cut the nylon strap to the desired length and burn the ends.

    Prepare the bag strap

    Place tear-resistant tape on the back of both P9 pieces.

    Prepare the bag strap

    Place the two snap hooks inside the P9 pieces.

    Prepare the bag strap

    Apply contact glue to the back of the P9 pieces, as well as to the ends of the strap (for about 4 cm).

    3. Prepare the chapes

    Glue tear-resistant tape to the back of the P8 pieces.

    Prepare the chapes

    Apply contact glue to the back of the P8 pieces.

    Prepare the chapes

    Insert the rectangular loops into the P8 pieces, then fold in half and glue. The pieces will be sewn in the next step.

    Prepare the chapes

     

    4. Prepare the flap

    Trace the location of piece P7 on the right side of piece P2, using an awl or a silver pencil.

    Prepare the flap

    Apply contact glue to the right side of piece P2 (in the designated area for P7) as well as to the wrong side (flesh side) of piece P7.

    Sew P7 to P2. Only sew the two lengths of piece P7 (do not sew the ogival end or the top width). Make two parallel seams. The bar tack stitches should only be visible at the top of the piece. At the ogival end, we recommend pulling the threads to the wrong side of the leather and tying a knot. Then secure the sewing threads with tear-resistant tape (see step 6).

    Using double-sided tape or glue, attach pieces P8 to the designated locations on piece P2.

    Prepare the flap

    Sew the two lengths of P8 pieces onto P2 (green lines on the pattern).

    Prepare the flap

    Glue the Salpa P4 reinforcement piece to the wrong side (flesh side) of the leather P2 piece, in the location indicated on the pattern. There is a margin of approximately 0.6 cm all around and 1.5 cm on the upper part (area where the flap will be sewn).

    leather handbag flap

    Glue the magnet to P2 in the position indicated on the pattern (about 2 cm from the ogival end). Reinforce the attachment with a cross of tear-resistant tape to ensure better hold and reduce the magnet's thickness.

    Apply contact glue to the wrong side of lining P2 and to the wrong side of piece P2 (leather and Salpa). Assemble the two, then press with a steel roller. Carefully shape the magnet's outline using a bone folder.

    Sew all around piece P2, 3 mm from the edge, except on the top line, which will be sewn later to the bag body (P1). Check that the presser foot can pass around the magnet, otherwise prioritize the zipper foot.

    machine sewing

    Using a rotary cutter, trim the excess lining flush with piece P2.

    6. Working on the decorative strap

    Apply double-sided tape along the entire length of piece P10, on the wrong side of the leather (or use glue).

    Fold each end of the strap over by 3 cm and insert a D-ring into each fold. Glue with double-sided tape.

    Stitch all around the strap in one continuous line 3 mm from the edge and start stitching in the middle without backstitching (for aesthetic reasons). Pull the threads to the wrong side and tie a knot. Secure the stitching threads with tear-resistant tape.

    Glue the magnet to the designated spot on piece P1 (centered and approximately 8 cm from the edge). Reinforce the attachment with a cross of tear-resistant tape.

    Glue the magnet with the correct side/pole so it can magnetize properly to the flap's magnet (test the magnetism as if it were the final assembly: wrong side of flap against right side of body).

    Working on the bag body

    Apply contact adhesive to the wrong side of piece P1 (leather + Salpa) as well as to the wrong side of lining P1.

    Working on the bag body
