Before the neo-trad movement, as many recurve shooters used sights as didn't.
Grants is correct. If you plan on shooting close range, most any sight will work, including most compound sights. Most decent (170 fps) bows need about 2" of vertical travel to reach 40 yds or so.
Peep sights are are NOT necessary, that's what your anchor is for and yes, a match stick is good idea before you shell out cash for a real sight.
Now for the bad news. AT close range, most people don't miss because of aiming problems. It's almost always some type of form for shooting technique issue. That's another reason TO try a sight - it takes aiming out of the equation and will reveal form problems pretty quickly. Yes, it's that unforgiving!
Before trying stringwalking there are easier aiming techniques you can play with, such as point of aim, where you use a reference point usually below the target and disregard the target entirely. Again, the idea is to turn the arrow or part of the bow into a sight.
