i believe "NAZAR" but i dont believe "blue eye"
but you are right jeanne , so many people may like it , good idea ;)

I like to present these carpet "bookmarks". My boyfriend has such a German translation of stories by Nasreddin Hodsha.I think it's aviable in various languages.It's really  made well and has a lot of nice pictures too.
Of course Turkish delight and Baklava is a MUST to bring home (to me ;)).
One time I brought a Turkish tea service set for my mother. I think it's a really nice gift and not so expensive.
I think also some gifts with the "Blue eye" are nice.

It was their special highlander tea and couple of stones that I pick up from the bottom of the sea . 

Lokums (Turkish delight) from Hacibekir (Istiklal cadesi No 83 Beyolu, Istanbul)
Just The BEST..... And of course apple tea.

yes you are right chaylak.. i agree.

I didnt mention earlier, that i have 1 souvenir that has been my favourite of all.
I got it in 1993 when i visited cappadocia and was trying to climb those rocks ..hehehe..

it was the exact volcanic rock stone which is crafted into cappadocia houses.(not sure what is it call in turkish)
i have kept it till this day and have always treasure it. I like it so much because its unique and although its just a miniature but it bring back the delightful experienced in turkey.
