I've noticed several comments about what can and cannot be carried onto an aircraft. According to the TSA website today, 6/29, the following policies are in place regarding needlework tools:
"Knitting needles are permitted in your carry-on baggage or checked baggage. Items needed to pursue a Needlepoint project are permitted in your carry-on baggage or checked baggage with the exception of circular thread cutters or any cutter with a blade contained inside which cannot go through the checkpoint and must go in your checked baggage.
Scissors - metal with pointed tips and blades shorter than four inches are permitted in carryon baggage."
