Next week I'll be fielding a unit of 40 Skinks and I plan to use both Lords of Space and Time and their inherent high movement characteristic to make them a highly mobile force. This will be my first time using such a large unit, though I did field 30 Skinks in last week's game, which was an object lesson in tediousness as I moved my carefully painted models back and forth across the board. Now, I'm told (and have read) that in the old days of square bases people frequently used "movement trays" to field large units. I'll probably eventually look for fancy bespoke movement trays to buy online, but for now, I'm trying to come up with solutions I can craft myself for my 40 Skinks in a few different formations (ranked, U-shaped, teardrop maybe). I don't think just cutting out some heavy stock cardboard or foam core and spray painting it a pleasing color will work, because I'm positive my trays will need some kind of lip or upraised edge to prevent models from falling off as the tray is inevitably jostled during movement. Any suggestions? I'm sure some of you good people have experience with this.
