Review on Maximize Your Thread Organization with the Arranger 60 Thread Rack by Will Ridpath

We bought and installed four of these. They work as advertised. The pins fit snugly but are easy to remove or reinstall and pull out or slide into the base; Fortunately, the pens don't use screws. Reviews warned that the shelf was difficult to assemble. They are not difficult, but tedious. The screws and washers are small enough to be difficult to hold on to, but the manufacturer includes enough in case you drop one or two. I wouldn't recommend trying to collect if you're in a hurry, but doing it while watching a TV show is pretty easy. The four we bought were attached to each other and formed a solid large board with 240 pins, ie 120 pins wide and 120 pins high. They came with equipment to attach to the wall. The necessary holes to attach the racks together have already been made, but the required bolts and nuts are clearly not included in the kit; Most people will probably only buy one. Because of the way they're constructed, you can attach blocks to make the rack as big as you want, which is good as we'll likely be expanding the 240 rack.
