You don't have to sew them. Just cut a square big enough to gather the
spices/herbs into, bunch it up into a 'package' and tie the top shut with
string. Usually double/triple/more thickness depending on the
weave/strength of the cheesecloth.

Check fabric shops for the material.

Other uses as well - straining paint - decorating for a 'faux' finish
(bunched into a wad) - and sometimes even for wrapping/straining/curing
cheese!!
