Cut plastic canvas round in half. Then cut away the inner circle. The arch should measure 10 meshes on either side.
Cutting tips:
Snip off any nubs of canvas with a pair of sharp nail clippers.
It may help to first draw a cutting line with a dry erase marker. Once canvas has been cut, simply wipe off the line with a damp cloth.
