Hello Antonio and welcome to PCC! What sort of things are you interested in making with PC? What sparked your interest?
There is a list of teachers at the following URL. I don't recall seeing Kenya listed, but there might be.
Fortunately there is a wealth of FREE online polymer clay resources as well as many books. There are written tutorials (called tutes) that can be downloaded, many for free. (see the URL to my list below)
There are also tutorials or or online classes or PDF-type classes that can be purchased: http://www.craftedu.com/ http://www.craftcast.com/
I have a generic post here at PCC that I love to share with new PC-ers that lists my hints, best beginner book, curing info, sites to get beginning info etc. Here is a link to the most recent time it was posted. It’s gotten so long that I’ve split it into two posts. So please check both of my consecutive posts.
p.1 is basic PC info (some of the links may be old or broken)
p.2 is a list of URLs to PC resources including tutorials (some of the links may be old or broken)
Check out Ginger's wide range of helpful info at www.TheBlueBottleTree.com
As far as where to purchase PC polymer clay there are online shops that I believe ship internationally, both from the USA http://www.clayalley.com www.polymerclayexpress
and the UK. I believe one may be owned by someone who is active here at PCC, but I can't remember who. I'm sure others will know and post the info.
also a good supply source info resource (though some info may be outdated) http://glassattic.com/polymer/supplysources.htm and scroll down to: Non-USA polymer supplies, etc.
I'm a fan of PREMO brand clay, but Fimo is probably the most popular European brand
Keep in mind when ordering PC that exposure to extreme heat while in transit can cause it to partially cure and make it impossible to work with. I live in a hot climate so, for this reason, only mail order clay during the cooler months.
Wishing you much enjoyment in your polymer clay journey.
