Quick tip: If you have no point protectors, use corks. When I went on a trip once I forgot to slip one of my knits-in-progress in my suitcase, so I asked my husband to bring it over as he was going to be joining us at a later date. He couldn't find my point protectors so he stuck wine bottle corks at the end of my needles before putting the project in his suitcase. It worked! Ah, the benefits of having a French husband whose grandmother was an avid knitter.
