I have been experimenting with a new product from the continent - I haven't seen it here in the UK.  It is called 'Ice' = this is Pink ice on a translucent flower.  So far it looks good.  

ClayAround now have not just single flexible blades, but also rigid blades and three types of ripple blades. Two of these blades are identical to those found in Fimo Cutters or in Sculpey Super Slicers, but one rick rack blade is larger.  And you canbuy them without having to buy straight blades too.  See here:  http://www.clayaround.com/index.php?cPath=35&osCsid=be650be795c467ed44076c632d2ba9f2 

Pardo professional Art Clay Translucent is the best translucent on the market!  See this example by Suie Corrie: http://www.pardopeople.co.uk/unsurpassed-translucent.html
