I've made a few of these envelopes recently. I suppose they could be a sort of clutch if made in luxury materials. The first one I made was the stripey fabric one. It was for my daughter to put a pocket audio player and headphones in. It was a last minute, midnight make. It's not perfect but she loves it. Then I made the oilcloth one to keep my travel documents in. It's very handy to keep all those A4 printed tickets you need these days and some passports in. The nude leather one is a present. Very simple and quick to make but a really handy thing to have. I've already used mine a lot.
