Rather chuffed with tonight's little experiment, I'd seen a video on YouTube that I now can't find grrrr, in essence you take a paper or cardboard cut out cover it in embossing ink, then clear embossing powder and heat until the powder is melted. Whilst its still warm you coat it again and heat it, and then a third time to give a good hard glossy coat.
Both examples were printed on A4 white printer paper using an inkjet printer, nothing special, so using 240g card and other weights of paper may have different results? Using laser jet images or items stamped with archival ink may also give different results. I'll do some more experiments over the next few weeks an blog about things that work and things that don't.
I used a stick on gem in the centre of my flower which I think finishes it off, just need to make a few more and I'll be able to attach them to a card and show the full effect. It means that I can make any kind of glossy toppers, tomorrow I'll experiment with shop bought die-cut sentiments and see what a bit of shine does to them. I love this learning curve, looking forward to the melt it powder and silicon moulds arriving any day now so I can use the heat gun to make 3D roses :)
