For the most part, polymer clay is pretty interchangeable. You can do a lot of things with all the clays. Of course, some are better than others. For example, while I’ve caned with Sculpey 3… it’s soft enough that it’s frustrating and hard to keep details crisp. I worked with Fimo Classic for the first few years but it was so firm I’ve switched almost exclusively to Premo, a much softer clay, to avoid pain in my hands.
Making the pretty faux sea glass above requires a good translucent. I use Sculpey 3 translucent or Premo White Translucent in my work but I know they’re not the most translucent clays… just the easiest for me to get and good enough. I’ve heard excellent things about Pardo translucent though and this faux sea glass is just lovely. Lucy of Craftberry Bush recommends the Pardo because she got the best results with it. I’d probably still try it with what I have on hand… I’ve done other faux with alcohol inks and translucent clays and I enjoyed the results. The old Fimo translucent was great for faux items that benefited from plaquing or spots such as faux stones but that wouldn’t be the case for this project.
