Ok - so a whole lot of flying embossing powder and several burnt fingers later - I will post my findings re UTEE and Inky doodles stamps! Firstly I melted my UTEE in a foil tray and not a melt pot so not sure how the temperature compares, but it was completely liquid and very, very hot. I used a versamark inkpad as a release agent on the stamp before pouring the moulten UTEE over it. I left it for about 5 minutes to cool and set, and then peeled it away from the stamp. The stamp was absolutely fine but there was still some UTEE stuck to it, whether I didn't use enough Versamark or this is all part and parcel of doing this technique I don't know. It was quite laborious to pick all these little bits off but a good rinse under a hot tap helped. The stamp has suffered no ill effects, unlike me with burnt fingers, but to be honest I struggled to find a suitable Inky Doodles design that would really lend itself to this technique, if anyone has any suggestions then let me know. So to sum up, it works, it does no lasting damage to your stamps, although clean up is a bit of pain, but it's not something I will be doing more of in the short term as I don't really think my designs lend themselves particularly well to the technique. Hope this helps!
