IKEA did not have any wine glass holders in stock. But, thankfully, there is a TORKAD paper towel holder. The hacking process can be seen in the pictures.
Firstly, you need to cut the part of TORKAD (there are two red crosses on the picture indicating that), I did that with an angle grinder.
Next, you need two wood screws and a wide washer. The washer is bent as shown in the picture.
Lastly, fix the narrow end of TORKAD to any surface you need.
You can fit 3 to 4 glasses in one holder.
