A lovely friend hand-painted and decoupaged a box for me. For the longest time I didn't know what to put in it - until the day when I finally became frustrated at my needle holder - it too was designed for straights, with a little zippered pocket for things like needle caps, cable needles and stitch holders etc. The pocket was too small for my ever growing collection of dpns.
Well, it dawned on me that day, I had this lovely empty box and it was just the right size! So in they all went. They are higgledy piggledy right now, but when I can find those small elastics, I'll be binding up the matched sets so I don't have to use the gauge to sort them every freaking time I want to knit.
You can do the same - I think she got the box at an AC Moore or Michael's.
