I thought you could do that with some organza designs. I know I've seen designs using thread snips somewhere and I think they were put between two layers of organza then hooped. I may be wrong as my memory isn't as good as it used to be! I'm sure there are others here who know what I mean and can perhaps explain it better. I've actually done the same with my thread snips, regular in one and metallic in another because one day I want to do this very same thing!
Good luck and hopefully someone will be able to explain better or point us in the right direction.

There is a jar design on cute that has clear plastic on outside that could hold snippets .

That is a great idea - I wonder which of the designers will do this for you? I am sure it would be a lovely angel.
