Tip for assembling this particular paint bottle rack: I am not sure I will use this as I bought this rack a long tiem ago, only now did I assemble it, and I think I will maybe prefer my bottles to stand vertically and not horizontally. But on to my advice.

Tip: This 120 paint bottle rack is tricky to assemble. Best use small clamps, but.. make sure you place a heavy object at the base, to make the two larger pieces come in good contact with the flat surface, then use clamps after gluing on things, one at at time. I used wooden glue and it looks like that works nicely.

I glued on the larger left side, before I finished gluing on the larger right side, as the final piece, and that final large piece was glued on, little by little, as it is connected to some 20 other parts. 😄
