della Que-i case for some time and decided to order it as a Santa gift to myself. I have a binder for the needles, but it is bulky and awkward in my knitting bag. I love the portability of the Que-i. My Knit Picks interchangeable needles fit nicely in size-labeled pockets, and the cables slip into the individual pockets below. Della Q also makes a double case that holds two sets of interchangeable needles.
Santa was a generous guy and also included a della Q Travel needle case for small projects. I must leave him some extra chocolate by the tree this year.
I ordered by cases from Jimmy Beans Wool, but a local yarn shop or any online supplier may also have them in stock.
I was not paid to put the above links in this post, I am simply a satisfied customer.
