How would you go about making this checkered tote look? Are these individual squares?  My squares on Minecraft cakes never come out as perfectly square and clean as these.  Any suggestions? Finally, how much would you charge for a cake like this?

ARoll out candy clay and cut it with a ruler -- use the ruler as you go to keep it level -- after it's applied roll over it somehow with a piece of paper placed between it and a fondant smoother or just your hand or if you have a dedicated paint roller-

probably around $8 - $10 a serving -- it would not be a big time suck for an experienced decorator--

if it became a five tier cake I'd charge exponentially more or if it was 16'

those are just plain squares yes? if they have texturing or more logos then definitely upwards of $10

also I'd only do this for a family cake due to copyright constraints

Thanks K8memphis!  When you say candy clay, is that the same thing as modelling chocolate?

yes
