Her website isn't up yet but I will post more tomorrow after I contact her. The one I couldn't get from Global Sugar Art was purchased at Design A Cake (www.design-a-cake.co.uk/
). I agree that it is cheaper to buy it here since the postage from the UK here can really add up. Six pounds is roughly $12 US. Once you add shipping and tarifs, it's cheaper to buy it from GSA.
I do know that her husband makes these by hand with special equipment they've had specially made. I like the large handle that these tools have since it makes it very easy to grip - easier than a standard fondant smoother.
Shirley, other than today, I've only used IMBC as well and I will not be coming over to the buttercream side anytime soon... LOL.
I don't think it would work with IMBC unless it were very chilled like you said. Definitely won't work with the Viva, darn it! But if I find a way, I will share for certain.
