Betty Shoulder Bag – PDF Sewing Pattern & Instructions

BETTY is a compact everyday shoulder bag with a front flap that closes over a magnetic clasp, and a webbing strap you set to your own length with a slider and two D-rings. The corners are boxed, so the bag holds its shape instead of going flat.

What You Will Learn

• Fitting a magnetic clasp: mark through the backing disc, make the incisions and set the prongs — on both the bag front and the flap lining
• Making and attaching the flap: sew three sides, turn, topstitch, then anchor it inside the seam allowance so it sits flat
• Boxing corners: pinch each corner, line the seams up, mark across at 5 cm and trim
• Building the side loops: thread webbing through a D-ring and stitch the loops into the side seams
• Threading an adjustable strap: webbing through D-ring and slider and back on itself, so the length is yours to set
• Bag-in-a-bag assembly: join outer to lining and turn everything through a 10 cm gap in the lining base
