To well-intentioned friends: consider simply inviting the two women you’d like to “fix up” to a party or function. Say a few well-placed words to each about the other, and then let things take their natural course - no “set-up”, no worries. Also, later on, you can ask each privately if they’d be interested in being set up on a date with the other - no longer a blind date. Try not to assume that they will hit it off together because they are both lesbians.
