I have had no problems with getting on board with these items. Just be sure your sissors have blunt ends. Mine purchased at LQS have little round balls on the tips. They are very sharp. I have taken both quilting and counted cross stitch with me and never had a problem. 14 days after 9/11 I flew to Greece with one of those cutters that look like a necklace and my blunt tapestry needles for my counted cross stitch.
