Reinforce the thinnest substances
For very thin and often transparent fabrics, depending on the project, the question arises of how to stiffen it, e.g. Sew buttonholes into a blouse or stiffen the loops for a great loop curtain so you can move it better. Here again the reference to the famous Vlieseline species, among which there are those that iron on / under such thin fabrics and are virtually invisible! Please ask in the department of a well-stocked department store.
