… this is the result.
I needed to use a tiny crochet hook, but didn’t have one with a handle… and they’re incredibly uncomfortable to use without. So I emptied the barrel of an old pen that doesn’t work anymore (better if you get one without the clip-thingie on top, as I’m sure it’d become annoying after a while), inserted the crochet hook, and cut enough of the ink-holder thingie inside to wedge against the hook to keep it in place. Taped the two together, and that’s all there is to it.
Of course you can use anything that fits inside the barrel to keep the hook in place, I just didn’t feel like looking all over the place for something pretty.
Yes, in my household, things that we don’t immediately remember the name of get called thingies. It happens a lot, since neither of us are native speakers of English.
