Facebook Suggest Friends
Step 1. Visit to Facebook and also visit your friend's timeline. Click the down-facing arrow with a gear symbol close to the "Message" switch.
Action 2. Choose "Suggest Friends" from the drop-down checklist. Scroll through your friends to locate the one you want to suggest, or get in the name right into the Search bar. Click the name to highlight it for sharing. You could choose multiple friends at once to suggest greater than one.
Action 3. Click "Send Suggestions" to send out the good friend tip. Both friends receive the recommendation under their friend Requests tab, which also tells them you made the recommendation.
