Hi Igor,
One trick i follow is drawing the switches with the physical connections and trunks. Then run over the Diagram and writing vlans numbers. Then check for transit Vlans. Lets say SW1 —-> SW2 ——> SW3 then if we have vlan100 in sw1 and sw3 and the only route between those 2 switches is through sw2 then you should add vlan100 to sw2.
