The technique on both of these cards is created with embossing powder and a sheet of parchment but I don't think it turned out quite right for me.
It was something that I watched Marion Emberson doing on YouTube and her cards turned out lovely.
So as you do I thought "Oh I will have a go at that" but this is my result.
I am adding the link here to Marion's video and if you try it then let me know how it goes for you
Marion has some lovely ideas on how to get he best from any embossing powders that you have and how to mix the colours to create your own, and they are well worth a watch.
I hope you cards turn out better than mine did here but I will give it another go and maybe make the powders a little thicker on my sheet.
Good Luck with it
Bye for now ...
