If you have an awkward space between walls in your home or a spot you'd like a wine rack but can't find something that fits, consider making your own out of some simple, affordable PVC pipe.
You'll want to make sure you get PVC pipe that's safe to use, like the type already used in your plumbing, and you'll want to get a size large enough to fit the wine bottles you have at home. Get them cut to fit your space at the hardware store, or you can take care of it with a hacksaw at home. Sand down the edges, paint the outside whatever colour you want (the walkthrough below suggests a flat matte white so you don't have to paint the inside), and just stack them in place.
If everything looks good, the tutorial suggests fixing the pieces together and to the sides and base of the space you're fitting your rack into with velcro. That way pulling out a wine bottle doesn't make the whole thing collapse, and since they're all painted evenly and cut the same, it'll look good in whatever space you slide the rack into. If you don't care for the PVC route, you could also use an old planter, mailing tubes, or even an old IKEA bed.
