Both retired from their day jobs, Dutch and Hammer are always working on new ideas, but have some luxury of time.
Most pieces for this exhibit came together just recently because of the way they work.
"We talk about the thematic elements," Hammer explained.
And sometimes the theme is a bit esoteric - like "Dreamsicle and Mint," the name of their largest piece in this exhibit, a floor screen that began with a doorframe.
The theme informed their color choices and harkens to the Good Humor man who used to drive through the neighborhoods hawking ice cream bars.
Dutch said they may not always agree totally on an idea.
"Robin usually starts with the idea. Even if I don't like the idea ... I know it's going to turn out fine. I'm kind of the structure guy."
As a piece comes together, it's a bit of a puzzle. In fact, Dutch said he'll often photograph the pieces as they're going to be assembled and then place them in a large Ziploc bag they use to keep the pieces sorted.
"We don't finish all the pieces at one time," he said.
Each is meticulous in the assembly.
Hammer uses multiple coats of paint, both hand-brushed and airbrushed, to create detail. He uses three types of sealing finish.
The two like to pay homage to favorite artists, both famous and local. A rolling dancer is a tribute to Matisse and a black-and-white table sculpture is a nod to Harold Edwards, a Charleston artist who makes detailed wooden sculptures he paints in bright geometric designs.
"We call it 'Harold in Black and White,'" Hammer said.
The two don't quibble over who put in the most time or effort into a piece -they've always divided proceeds 50-50 and making sure they set aside money to re-invest in supplies and equipment.
"In the end, it always works out," Hammer said.
