I'm looking for a small flat piece of metal pretty much like the ends of a head fastener. Any ideas what I could use. I tried to cut the pieces out of some metal sheets but they ended up with rounded edges and bended up too bad. I also tried the ends of the fasteners but they are to limber. Here is a pic of a fastener to get an idea:

How about decorative upholstery tacks? Maybe thumb tacks if you can find unpainted ones.

Those things have a rounded point on them don't they? I'm looking for something longer and flat. The ends would be perfect on the picture above but they are just too flexible, they bend and don't hold their straight shape. I need a piece like that but stronger.

What about the tines on a grass rake? You may have to grind them some to get the size your looking for, but the metal should be stiff enough for whatever your doing.

That is a very nice idea. That will get costly after awhile, but that is on the right track.

You might be able to find a bunch of unnamed, unidentifiable stuff at a junk yard.  Take a stroll around there and see if you can find any scraps that might work out.  Maybe there will be 100 rakes on sale  ;D

look in the school stuff isle at wally mart.   Those things are in folders sometimes or sold seperately.
