Over the past 20 years I’ve acquired (and lost) a lot of circular needles. I did give interchangeables a try at one point, but somehow all that remains is a single matching pair of Denise needles.
For a while I used a big binder full of binder pouches for storage, but it was bulky, so I made this instead. I used handheld pipe cutters to cut lengths of 1 inch PVC pipe, glued them together and hung it on the back of a closet door hook with a cotton cord.
It is not the most visually appealing, but it works for me, and it sounds like a rainstick . The short pipes mostly have 16” and some 20/24”. The longer pipes are mostly 40” (I prefer magic loop, so I’ve got a bunch). Not pictured here are the many needles stuck in unfinished projects, lol.
I have a set of circular needles with interchangeable needles and lengths of wire/nylon. It all fits in a little case the size of a small notebook. I have a second set of sock size ones that are a bit sturdier and have steel needles instead of wood/bamboo.
