Making beautiful quilts requires space for cutting and storage, so when Ellis saw an 1860s terraced house with a pretty rear garden and a modern studio, she knew she had found their new home.
"The garden was really well designed and planted [but the house] was a horror of rainbow-coloured walls, layers of wallpaper, dirty blue carpet, and dodgy plumbing and electrics."
However, almost all the original interior joinery and fittings, from cornices to doors and fireplaces, were intact.
Ellis and Prichard did a lot of the work themselves, between September and November 2010. "We did everything but the plumbing and electrical replacement," she says.
After stripping back the floors, Ellis painted the upstairs boards a pale grey, while the ground floor was finished with natural hardwax oil.
The walls are off-white, and strong black "punctuation points" are features of the house, embodied in black iron radiators, painted doors, door frames and smaller decorative items. In the kitchen, glossy white cabinetry is teamed with a black painted antique cupboard and the benches are recycled laboratory worktops. The only patterned fabrics in the home are in the riotously colourful quilts on the beds.
The result is a space that's neither too spartan nor too cluttered. Artworks provide interest in the living spaces.
Ellis says quilts often mark milestones in people's lives.
"When people commission a quilt I ask them to give me things like pieces of favourite clothing, dress fabric or even old toys. A quilt is all about personal stories, from a marriage to remembering a child. My quilts are to be used for keeping warm and storing memories, though - they're not just precious art."
Style tips
Simple pleasures: Having something made for you by an artisan or craftsman is a real joy, from commissioning a work to watching it being made and bringing it home.
Exercise restraint: Because Ellis' house is small, she chose a simple interior colour scheme so it wouldn't look cluttered and cramped. But simple doesn't mean just using white; pick a simple theme and follow it right through.
Structured look: Investing in the bones of a house - the floors, walls and doors - pays huge dividends, especially in a character home.
