Hi Karen,
some places to find fondant/gumpaste 'how to' information and tutorials are:
www.cakejournal.com and www.CakeCentral.com, on YouTube there is a lot of information available.
for example if you search for 'Mystical Mischief ' you will get lots of video clips from Elaine Thomas a very talented British cake decorator.
Places to buy cake decorating supplies in Israel you can also find on the web, but it is better to go to a shop in your area because they have usually more in the shop than the things shown on their website and you should see what you are buying, these things can be expensive. I buy from 'Mamlechet Haofim' in Nesher but there are other shops, just type ' tsiud lebatsek sukar' in hebrew and see what you get.

thank you so much for your response, i will look for it!

Hi Karen thanks for friending me, I saw you wrote you are looking for places to buy decorating stuff in Israel, if you ever get to jerusalem there are a bunch of stores here, there is a Wilton store, there is a store called 'Lashef', I think there is one called 'Mana Achrona' and if you need only fondant than most Pe'amit stores sell it. good luck :)
