I am using Detolf shelves from IKEA along with baseball cubes and hockey puck holders to create variation in height (riser effect) from back to front. It is beneficial to have some detail brushes to dust off the helmets and nooks/crannies on the bobbles. I have all the SGA bobbles from 2001 to 2022 and this is just a video of the 2015 to 2022 I have placed in display so far.
Best Baseball Cube to use: both pieces are square and there isn’t any plastic on the bottom side to hold a baseball in place. When you take the cube apart both pieces are identical matches: A little pricey but worth it:
