Perfect For

  • Adventurous beginners ready to tackle their first structured bag
  • Sewists who love working with alternative materials like cork or vinyl
  • Anyone wanting a versatile everyday crossbody they can make in multiple colourways
  • Gift-givers looking for a handmade present with a high-end, boutique look

Tips for Success

  • Interface everything: For fabric versions, a fusible woven interfacing on the exterior pieces will give your Gemma that structured, polished look. Skip this and it can look soft and slouchy.
  • Test your zipper foot: The zipper pockets and magnetic snap placement are the trickiest parts — do a practice run on scrap material before cutting into your feature fabric.
  • Watch the videos first: The included sew-along series is genuinely helpful. Even experienced sewists benefit from watching before cutting — the angled seam assembly has a specific order that matters.
