Check with the airline and customs first. I had to part with a cherished favourite pair of scissors not allowed in the cabin while flying in the Cdn North where there has been no terrorism for centuries. Now I ask to take the finest 7/8" needles, a whole lot of precut thread, a needle threader and I have one of these little circular clover discs with a rotary blade sandwiched between the 2 halves. It is completely safe, to open it requires a pocket knife which is not allowed on board, fabric, and that's the sewing kit. Otherwise a magazine of pattern book, notebook and coloured pencils to plan the next project?
