My favorite means of creating a quick legend is:

(* Plot    *)
Plot[{x, x^2} , {x, -10, 10}, PlotRange -> All,
 PlotLabel -> Grid[{
    {Graphics[{Blue, Line[{{0, 0}, {1, 0}}]}, ImageSize -> {20, 20}],
     "Scope"},
    {Graphics[{Red, Line[{{0, 0}, {1, 0}}]}, ImageSize -> {20, 20}],
     "Other"}},
   Alignment -> {Left, Center}, Spacings -> 0],
 PlotStyle -> {Blue, Red}]

I can't take full (or any) credit.  This discussion came up a while ago and I happily scavenged these ideas from others.  The key is Grid[].  Play with it a while and it will grow on you :)
