What you’ll make
Make an insulated crossbody bag for carrying lunch, drinks, or containers to work, a picnic, or a day outdoors.
The boxed base adds depth, and the top folds over and closes with webbing and hook-and-loop tape. An adjustable, removable strap attaches with swivel hooks and rings.
What you’ll learn in this class
- Assemble contrasting exterior panels.
- Sew a webbing and hook-and-loop closure.
- Handle insulating fabric without puncturing it.
- Create a boxed base in both bag layers.
- Join, turn, and secure the thermal interior.
- Add swivel hooks and thread an adjustable strap.
Fabric and supplies
Use exterior fabric, insulating fabric, bag webbing, hook-and-loop tape, rings, swivel hooks, a strap slider, and water-soluble fabric glue.
Use sewing clips rather than pins on the insulating layer. If the exterior fabric is very light, add interfacing for support.
Make it your own
For a regular crossbody bag, omit the insulating fabric and use cotton lining. If the insulation has no silver surface, add a separate inner lining.
Choose the crossbody strap length you prefer, then add the slider so the bag can be worn higher or lower.
Sizing
Finished and closed, the bag measures approximately 22 cm wide by 26 cm high by 10 cm deep. Open, it measures about 35 cm high.
The complete class includes a downloadable project PDF with finished dimensions and a cutting layout for the insulated bag.
