What you use depends a bit on how much space you have for containment while traveling. I found a number of different sizes of containers where they sell fishing equipment to be very useful for portable needlecrafting. The bags (soft sided) or hard plastic containers usually have adjustable insides so you can make space for your tools, finished and unfinished pieces. Now that we are past the holidays, the sports stores will start gearing up for fishing, so you may find a good selection that works for you.
