I'm a former knottie bride (little over 3 years ago

) and I'm now hosting an engagement party for my BFF. Her parents are not in a financial position to contribute to the cost of a party and she asked me to host one for her - which I don't mind. However, I myself *didn't* have an e-party and I've never been to one. Here are my questions/challenges:1) What's typically expected at the event? We've already decided to host it at their home with a backyard bbq type feel. Are there any formal activities I should prepare for? Toasts? Are gifts expected?2) Do you have any ideas about how I can involve BFF's parents *without* asking them to financially contribute AND without making it a slap in the face that they couldn't afford to do the party?Any other thoughts?TIA
