About
Hi, I'm Jill.
I'm an interior designer based in Southern California. I work with people everywhere through flat-rate online design, consultations and staging. Your Design Guide is where I share the practical side of design — layouts, furniture, color, lighting and styling — so you can make confident decisions in your own home, whether you follow a guide, join the monthly challenge, or hand a room over to me.
