FULL TUTORIAL VIDEO

 

1. PRINT AND CUT THE PATTERN

Purchase the paper or PDF pattern (print at actual size).
Seam allowances are included.

Cut out and then trace the pattern pieces onto the leather using a silver pencil. Mark the centers of each piece with a pencil or make a small 1 mm notch (see pattern).

3. OPTION: Fanny pack personalization

OPTION: personalize one of the P1 leather pieces.

4. Glue the P5 strips

Apply contact adhesive to the back of both P5 strips.

Glue the strips

Glue back to back, then press with a roller.

Glue the strips

From this strip, cut 2 straps: a first one measuring 2.5 x 25 cm and a second one measuring 2.5 x 95 cm.

Cut the strips

 

5. Skive the ends

For assembling the P5 straps with the rest of the fanny pack, thin the ends of certain pieces to reduce bulk and facilitate sewing. To prevent the leather from tearing during this operation, apply tear-resistant tape to the indicated areas of the pattern, on the right side of pieces P1, P3, and P4. Be careful not to exceed these areas, as the tape might become visible once the bag is finished.
