Published earlier this year, Sean A Pritchard’s second book, , deconstructs the colour theory and technical nous behind mood-lifting floral arrangements, with each principle brought to life by his own photographs: Icelandic poppies in a glass jar at Kettle’s Yard; a Chinoiserie vase of love-in-a-mist at Richard E Grant’s Georgian home; a ceramic tankard of “fried-egg daffodils” at Charleston… “It’s about bringing together all sorts of combinations of flowers and backdrops to produce these sensuous moments,” the garden designer, a confirmed maximalist, says. “Different juxtapositions of colours, scents, materials and textures produce different effects – not just aesthetically, but emotionally.” Depending on the season, his own 18th-century cottage in Somerset’s Mendip Hills might be filled with Boscobel roses or catkin branches, forced hyacinths or bright dahlias, the blooms dotted amongst his “hodge-podge” collection of Delft plates and Welsh tapestries, Robert Kime cushions and Rosi de Ruig lampshades.

Now, Pritchard is lending his floriferous taste to his inaugural pop-up The Emporium. Set on Great Portland Street, the shop translates the playful, polychromatic feel of to “the design world more broadly”, with the author transforming a minimalist Marylebone space into a festive bazaar using Vreeland-red Rachel Chudley paint, drapery inspired by Napoleon’s bedroom at Château de Malmaison, and lashings of tinsel. Along with flowers in every form – including daffodil ornaments hand-blown by Germany’s Marolin Manufaktur – dozens of makers, founders, curators and artists will showcase their work and wares from now until Christmas Eve, with exclusive designs by the likes of silversmith Heath Wagoner and ceramicist Joseph Dupré, whose works featured in British ’s recent cover story with Daisy Edgar-Jones.

As The Emporium opens its doors, seven of the craftspeople and creatives involved share what they’re giving – and hopefully getting – this Christmas.

What’s on your Christmas wish-list this year?

An Asymmetric Vase in Translucent Alabaster from Flow Gallery… This would have to be from someone very generous, but perhaps I have a secret well-wisher who likes to bestow beautiful goods on the not-so-deserving? – Charlie Porter, founder of Tat London

The Unsettling of America: Culture & Agriculture by Wendell Berry, Shepherd of Sweden slippers and anything from Dunton Ellerkamp’s most recent jewellery collection. – Alex Crowder, founder of Field Studies Flora

A hand-built owl nesting box from Backroad Goods. – The Bible of British Taste

Roses by David Austin, vintage Chicago blues LPs, a Gränsfors Bruk Small Forest Axe and king-size Volga Linen bedding. –

A Braun Nizo 801 Macro Super 8 Cine Camera and lots of film. – Freya Marton, founder of Black Lion Workshops

Anything from House of Aquila. I love her jewellery so much. Last year I was given a little fire-horse pendant and haven’t taken it off. –

Isamu Noguchi’s Akari UF3-FF. – Olivia Thorpe, founder of Vanderohe

Any tips for getting festive decorating and hosting right?

Buy The FT. It’s an excellent newspaper, obviously, but once you’ve read it, turn it into paper crowns and diamond trimming for your shelves. To complete the look, dry some orange slices for the tree and buy some nice ribbon. It might look slightly 1940s, but who’d complain? –

A big armful of old man’s beard from the hedgerow, draped over the mantelpiece. –

Never use overhead lights, and – of course – make your own paper chains. –

Eat in the kitchen, with buckets of excellent claret and Pentreath & Hall candles. –

I tend to keep my decorations as natural as possible: little beechnuts hung with velvet ribbons; sprigs of evergreen foliage balanced on top of picture frames; and a pine garland over the mantel which releases its scent when the fire’s lit. I also love scattering the house with our brass artichoke-shaped candlesticks, which cast star-shaped shadows. –

Stick to just one colour; this year, I’m going to decorate the tree with pale, ice-blue ornaments, and I’ll carry that through to the glassware, candles and linens. –

Decorate for yourself! I love the smell of a tree, so I lug one up four flights of stairs to my apartment every year, drape it with string lights, then leave it up well into January. –

What’s the best gift for…

You can’t go wrong with Bridie Hall’s soaps – useful and joyful. –

Twenty-five lottery tickets. –

The latest issue of The Bible of British Taste magazine. –

Beeswax taper candles and matches, bound with twine. –

Traditional Japanese Floral Incense Cones from Choosing Keeping. –

A huge pot of black, pitted Moroccan olives – the most delicious olives I have ever tasted. –

I’d be thrilled to receive one of Compton Marbling’s candle boxes… It’s two gifts in one. Pair it with something from Santa Maria Novella, and I’d be over the moon. –

St Peter’s Candlestick Holders from Black Lion Workshops, which are making their debut at The Emporium. –

A pot of almost-flowering paper whites. They’ll open around Christmas time. –

Vanderohe Nourishing Face Serum with a glass orb to keep in their bathroom. –

A no-brainer: a subscription to The World of Interiors is essential reading for any aesthete. –

A Friend of the Royal Academy pass. –

One of my six-foot, chip-carved ash dining tables. –

A first-edition hardback by Iris Murdoch in a beautiful dust wrapper. –

You can’t go wrong with a bouquet from your local florist, tied with a long ribbon. –
