After visiting an endless number of designer show houses and poring over portfolios, Newsday has pulled together 11 designers, including one husband-and-wife team, who bring beauty and drama to Long Island’s homes. We’ve taken a peek at what they’ve been up to recently and learned a little more about what makes each of them stand out from the pack.

This week, we chat with Katharine Posillico McGowan of Katharine Jessica Interior Design in Huntington.

What is your favorite DIY tip?

I was taught this DIY tip from my decorative painter, and I use it all the time. Rub’n Buff Metallic Wax is an easy way to freshen up or change the look of almost anything. You simply apply it with a cloth and then buff it once it is dry. We have changed the look of light fixtures, antique furniture and frames. It is available in silver, gold, pewter and many other metallic finishes.

What design trend are you so over?

I am so over “Fifty Shades of Grey” or Fifty Shades of Anything, for that matter. This meme has traveled across all industries and continents. It has especially hit the interior design world hard. Gray is still valid, but please, let’s incorporate color moving forward.

What is the cheapest find you have furnished your house with?

In my mudroom, I have a bench I found at Home Goods. It is a rustic blue wooden bench with a lovely shape. It was $150.

What is one piece in your own home you couldn’t live without?

The custom square ottoman I designed for my family room. It has an inset silver metal tray in it and is upholstered in a blue stripe velvet

Which project are you most proud of?

The project I am most proud of has to be a renovation project I did for a family who had recently lost their 1-year-old daughter to cancer. I was honored to be able to help design a retreat for them to create beautiful memories as their family began to move forward after an unthinkable tragedy. I am so proud I was able to help in their healing process. The biggest honor is that the home belongs to my brother and sister-in-law.

Which other designers do you admire?

I admire so many, specifically Andrée Putman. She was a woman before her time and was always a forward thinker.
