How beautiful! To carry out these tasks we must mainly bear in mind that we must like it and have a lot of patience.
I'm from Venezuela, here this material is called mostacilla, we call this work costume jewellery, as a girl I did many of those tasks: embroidering necks, headbands, earrings.
I remember that once I bought a nice blouse with a very nice embroidery, but it was ugly, I undo it, I bought everything again and I embroidered it again.
