Checked with TSA. Scissors with point smaller than 4" OK. But I'm not risking my expensive clippers, so I have a tiny blunt pair to snip thread. Pins and needles are OK too but I'm using Clover clips and a tiny needle.
They have to allow a sewing needle or they have to start taking safety pins. My husband retired from Home Land Security.
Quilting candy, I don't use papers, I mark and do running stitch.
