I have a dear friend that loves to sew/quilt and she has made some lovely things for me. (Gorgeous quilted knitting bag!) Since I love to knit I'm always gifting her with something hand knit. Works out great for both of us!
At the present time I have my straight needles in a plastic cylinder that was made just for knitting needles, but it drives me crazy because I still have to dump them all out to find the right size and two that match. Anyway my friend is going to make me something like the link I'm posting. You can buy these in stores or online too. Lucky me, my friend is going to custom design my case!
