During a right downwind departure from runway 31R at boeing field I inadvertently penetrated the edge of class B airspace of seatac airport. Upon contacting departure control for flight following to pdx, and permission to climb through the class B airspace, I was advised that I had clipped the edge of class B, and that I should watch it more carefully in the future. Upon reviewing the VFR terminal chart more closely, I see that I did in fact climb to 1500 ft too soon. I have reviewed all airspace requirements around boeing and seatac, and in the future will double check VFR terminal charts immediately before attempting VFR flight in the affected areas.

UPON CONTACTING DEP CTL FOR FLT FOLLOWING TO PDX, AND PERMISSION TO CLB THROUGH THE CLASS B AIRSPACE, I WAS ADVISED THAT I HAD CLIPPED THE EDGE OF CLASS B, AND THAT I SHOULD WATCH IT MORE CAREFULLY IN THE FUTURE. UPON REVIEWING THE VFR TERMINAL CHART MORE CLOSELY, I SEE THAT I DID IN FACT CLB TO 1500 FT TOO SOON.
