 Heather is wonderful to work with as an interior designer! I’ve worked with her on and off for nearly 5 years on projects both big and small at our home in Wayne ranging from major kitchen and living room renovations to simply getting her expert advice and selection ideas for décor, paint color, backsplash, furniture, room layout, hardware, light fixtures, and other design decisions. She seems to know about EVERYTHING when it comes to the home and can recommend high-quality décor or furnishings that fit within a budget. Heather has lovely taste and seeks to understand your style, lifestyle needs (eg, kids, no kids, pets, etc) and will give design ideas to maximize both the look and functionality of your space. Finally, she has a great way of communicating and when asked for an opinion, she’ll give it to you openly and honestly. She makes what feels like an overwhelming process with lots of decisions very fun and enjoyable.

 I have had the pleasure to work with Heather and Main Line Design on two different projects over the years. Heather blended my existing furniture and art with some new purchases. She really listened to my needs, solved problems and stayed on budget. The previous owner of my last apt come over and saw the finished worked and said, "this place looks like a magazine cover". I think that's the best complement I could get and that is all because of Main Line Design.

Heather is super friendly, easy to work with and practical. She will take her time and give you her honest opinion.

 I have had the best experience working with Heather on several different projects in my home! I needed her help when trying to make updates on our older house and loved the ideas and recommendations she gave us! Highly recommend Heather for all aspects of home interior and design!

Furnishing our newly bought house was an overwhelming project for both my husband and I.To say we didn’t know where to start would be an understatement. Little did we know that we would have an expert interior designer right next door, Heather.Her ability to see our vision and share her practical advice gave us the confidence to purchase the right furniture and position the decor that was meaningful to me in a cohesive layout. Every time my husband and I were unable to agree on a color or layout, Heather would come to the rescue!  She always balanced her advice by taking into consideration my inspiration and his practicality. Over a course of five years, (as my husband moves at a slow pace), the house seamlessly transformed into what feels like "home".  Heather came along on this journey and helped us to create a warm and comfortable place that we adore.

Heather not only knows design like no other we have ever used. She will quickly get to know you and create a design that exactly what you want and what your style is. You can't go wrong. She is attentive and will be at your side the whole time and has so many contacts in the industry that she will find and work with the best contractors for your project.

Heather is wonderful to work with. Interior design is not in “my wheelhouse” and she really taught me a lot! She truly listened to what we wanted to use the room for and designed accordingly.  She has an eye for colors, styles and creative solutions! I love our new living room and loved working with her!
