As we didn’t find any shelf of our liking we tried to create it ourself. It worked out better than expected, however it obviously isn’t perfect. But as completely laymans we are happy nonetheless.
One cool feature is that through all pieces goes one straight hole, this allows putting lamps on the shelf without seeing any cables.
Yes that's true, and I think at least in this case the imperfections are acceptable because the desired look was to feature the organic look of the wood. At least it's a good excuse for the lack of woodworking skills
