I recently went traveling and i came across a problem; i was scared my knitting stitches would come off when i kept in my bag. and if you are a knitter, you know how painful losing stitches is.
if you dont have those knitting needle caps or stoppers, try this:
use a rubber band or hair tie. then you just tie the knitting needles together at the top in a sort of infinity/number 8. tie it really tight. know your knitting should be able to withstand the jostle of the inside of your bag and you can enjoy the rest of your trip without worrying about dropping stitches!
hope this helps.
