Make a totally unusual ROUND, circular, non-quadrangular bag

Step 2 Cut and interface your pieces:

- Trace and cut a perfect 26 cm circle in one corner of your fabric. A low-tech way to do this is to find a centre-point, then mark dots 13 cm from it in every direction.

- Trace and cut the same circle once from your interfacing and twice from your lining material.

- Cut an almost-square 26x28 cm from your main fabric. This will make the zipped panel. (The extra length is seam allowance for the zip.)

- Cut the same piece from your interfacing and lining.

- Cut one strip 42x10 cm and two strips 42x6 cm from your main fabric, interfacing and lining.

- Iron the interfacing onto your five pieces of outer fabric.
