I do it in the following way:

1. for one string:
 const char szErrorInfo[] PROGMEM = ("Error");

2. for table of strings:
#define CMD_HELP             "HELP"
#define CMD_HELP_CHAR  "?"
#define CMD_EXIT               "EXIT"
PGM_P szProgMemCommands[15];
void InitSetup( void)
 BYTE iCnt=0;
 szProgMemCommands[iCnt++]=PSTR( CMD_HELP);
 szProgMemCommands[iCnt++]=PSTR( CMD_HELP_CHAR);
 szProgMemCommands[iCnt++]=PSTR( CMD_EXIT);
 szProgMemCommands[iCnt++]=PSTR( CMD_PASSWORD);
Maybe it could be possible to make it easier but it also works...

I want to do following
Create array of pointers to strings in program memory. Strings also must be in program memory.
I try following:
PGM_P str_table[] PROGMEM = { "ERROR", "OK" };
I get
00000026 <str_table>:
  26:   61 00 67 00
Contents of section .data:
 800060 01455252 4f52004f 4b00               .ERROR.OK.
Compiler put pointers to prog memory but I can't make him to put string there.
Any Ideas?
