I too recommend the Clover pendant. I take my hexies, fabrics, threads, needles, bulldog clip in a quart plastic freezer bag and wear the pendant. Never had a problem. But I do take off the pendant when going thru security. The rest of my fabric and hexies are packed in the suitcase. I also take a sample with one row around the center, someone always asks what I am sewing. Then I can just show them and not have to explain.
