I used this elastic to make numerous masks. Its actually a bit softer than a lot of the standard elastic you can buy. It is a little thicker, more like a smaller shoe-lace.
I would recommend buying this if you're trying to make your own masks at home. It is a little thicker so make sure the loops you tie it through can accommodate it. Great value for the money - I didn't realize when I ordered this how much 30 yards of elastic is!!
Disclaimer, I did receive this product at no cost as a trial, however I intend to purchase the item again when I need more elastic!I would use this for other projects in addition to masks, very versatile strong elastic.
