I have an eyeglass case, one of those tubular types that are sold with those inexpensive readers. Someone gave it to me about 10 years ago. I don't keep all of my hooks in that because I have too many, but it is perfect for what I need to carry in my tote bag. I am mostly a knitter, but I also crochet, and a hook is essential in case you drop a stitch and are away from home.
I keep my everyday hooks in a plastic case that came with my set. For hooks that I've acquired individually over the years, like the bone hooks or my grandmother's, they are in 'pen holder' sleeves in a pen holder portfolio. The rest are all stuffed in a large stiff flat bottomed pencil case. The case can sit upright on my table without falling over.
I have a special container that I received one Christmas, it is a limited edition Tia Maria carrying case, it is long with a metal lid on it meaning I can carry all my hooks (including tunisian!!). If I find the online picture I will update - but I recommend these types of carrying cases although meant for alcohol they are perfect for carrying hooks & tools also!!
I keep my hooks in relatively large cosmetic bag, and keep that in a satchel that also holds all of my other knitting and crochet tools (knitting needles, hooks, tapestry needles, etc.). Though it's reaching a point where I might need a bigger satchel, LOL.
Love this topic. I have several places, depending on the size and brand. I have 2 cases I got online and another off etsy. Then I keep the little ones in a nice jar with a lid to keep from losing them. Pencil boxes work great too as I’ve used them in the past.
I have a seven section pencil case that I keep mine in. If anyone would like to see it I am more than happy to take some photos tomorrow in the day time and post them on here. It makes life so much easier having them this way
