How do they get the tape so curved?

[comet22]

Any ideas on how to get that perfect radius, any help would be good.

thanks

I'm not really sure, but I would try to find some sort of white material with an adhesive back. Then i would buy a large sheet of it and just cut the radii.

This is from the person who set up the tape on our field:

This seems kind of long and boring, but try this:

2 in. pieces placed in spots.
Make sure the arc is a 4 ft. radius.
