My picture rails were so full I had to do something about it. I ordered three ink pad towers from Netherlands. Unfortunately not the best quality, but nothing that a little glue and spackling paste will not fix. I put all three towers together and painted it white. I used some walnut stain on it to get a more shabby look.
It holds all 36 colours. I keep my distress ink tag pad on top of it.
And now to the embarrassing part. I´ve got 25 ink blending tools. And yes. I use them all.
I drilled some holes in a leftover beam and put some blocks in each end of it. I´ve used tons of alcohol inks to colourize it. Don´t remember which ones I used. It´s five ft long, so I´ve got room for more tools.
I keep distress ink refillers, distress stains, distress stickles, distress crackle paint, distress embossing powders and tons of other stuff on my picture rails over my desk. Reachable and totally in view.
