Cut fabric with pinked edges and serger thread cones on a green cutting mat

Know what’s on the shelf before you start cutting.

Sewwing keeps your serger thread, fabric, supplies and machines in one place: sorted by colour, drawn to scale, and on your phone when you’re standing in the fabric shop.

New accounts start with a sample stash you can edit or clear.

Every cone, by colour

Thread is filed the way you look for it: by colour. Counts change with a tap, and anything down to its last spool is flagged before you run out mid-seam.

Fabric, drawn to scale

Each cut is laid on the mat at its true size, so two yards of suiting really looks twice a yard of voile. Weave, fibre and width read at a glance; add a photo and it shows instead.

One yellow square is a yard of 36″.
