Does your friend live in Lebanon or just have her wedding in Lebanon?
I had my wedding(anniversary)party in Lebanon last year. Also something very unconventional...
Had to leave a lot of the gifts with my inlaws as they were to big/heavy to take back home by plane. I got jewelry (necklaces and/or earrings are common), ABC giftvouchers, money, cristal candlesticks, silver serving platters, fur jacket, luxurious wine opener set, silver photo frames...
This summer I also had a wedding from my husbands cousin. We made a little gift basket with Dutch products and added an envelope with €100,-. (Don't know if this is appropriate, but we don't really care...).
For another wedding we got them some art (prints) and a handmade necklace.
If they are truly friends they don't care what you give them. You being there should be enough!!!
