The next step is to gather the filling ingredients. Shredded egg crepes, cucumbers, squid, salmon (either cheap smoked salmon or sashimi), and fresh, sashimi grade tuna. This will complete your color palatte of yellow, green, white, orange and red. Aside from the shredded egg crepe, all the ingredients should be cut lengthwise. For adults, use squid or salmon, together with a touch of wasabi.
