Some of you out there might know Lisa, mom to Lucas and Theo, and the epic DIY-er behind this adorable “Letters & Numbers” themed birthday party. Lisa is a craftswomen by trade, as the proprietress of Good On Paper Design. (We’ve showed her work over on 100LC many times!) She went big in the creative department for Lucas’s birthday. Such a cute, (and realistic!) party hosted at Tilden Park in Berkeley. Parties at a park give the kids so much room to run and play – plus it’s a free space!
