Welcome! (^^) I purchased this for the lining of handmade masks. It's smooth, thin, and has a slight stiffness, so it doesn't stick to your mouth. It's perfect for handmade masks! It seems like it's not readily available at craft stores. I happened to find it near my previous home and have been using it ever since ^^ It's like the interfacing for the facing of blouses, but... I had a flash of inspiration ♪ Original ✨️ I can't even count how many times I went to buy it! After a while, it was cut and displayed as mask lining in the handmade mask corner of the display table ✌️ It's a treasure that made me excited during that scary time ♪ I bought too much of this color though^^; It can be used with any outer fabric that isn't see-through ⭕️ Width: ~90cm Length: ~50cm It will be folded and sent via Post Mini. 7☆ ー∞ー#HandmadeMaskLining #CraftSupplies #Interfacing
