I saw this blog showing how to make a traveling pin cushion and thought, “What a good idea!”  http://www.rileyblakedesigns.com/cutting-corners/2012/08/03/traveling-pincushion/ This is soooo cute.  For us lazies who are okay with a plain cushioned top over a container, though, this can be adapted.  You could probably get one of those paper boxes at a craft store, cover it with fabric and then cushion the lid.  You could also attach a pin holder to the inside of the lid.  It would safely keep your items together and would be great for us who like to do handwork while we are out or traveling.
