Most airport security officers, including TSA, and airlines indicate that you can bring sharp objects with blades up to 4 inch (~10 cm) in the carry on luggage. This means that you should be able to bring small embroidery scissors with you. But regulations change now and then. So if you want to be sure you can either follow our golden tip 🙂 or call your airline to get the latest security rules ( yeah waiting 30 min on line 🙁 ).
Our golden tip: Cut your fabric to size before traveling. Then you’ll only need a sharp object to cut your floss. And you can easily cut your floss with nail clippers. We’ve never had issues bring those in the plane whereever we travelled in the world.
A tooth floss holder can also work. Remove the tooth floss and use the sharp cutter to cut your floss.
