Step 2: Trace & snip

Picture of trace & snip
NB: Fabric should always be pre-washed to shrink and ironed or relatively flat.

Fold fabric to accomodate the surface area of you plate. Trace plate and cut 2.
Repeat this step on same or different fabric to produce 4 circles.

Side Panel:
calculate your circumference in order to know the needed length of your side panel:
Measure your diameter (the full width of the circle) and multiply it by 3.14, you know... Pi!

You do not need to subtract the length of the zipper as the extra will serve as a handle,
see what I did there?

You should cut out 2 strips that measure the length of the circumference and the width of the zipper.
