Hi! I have never made modeling chocolate using almond bark but I thought since no one has replied yet I was respond with what little I know and give you a bump. I know someone and have heard from a few others that they use it and it works great. They just substitute the candy melts with the almond bark. No other recipe changes required. I have been told that the almond bark and syrup don’t seem to mix very well at first, but once it sits for several hours it’s fine.
