Max out on fabulous fabrics for windows, walls, sofas, tiles, lights and more in this free-admission patternfest. This is the capital's catwalk for interior design, and everyone who is anyone in global interiors will be there.
The programme includes launches, lunches, celebrity talks, seminars, demonstrations and free drinks, all in the three glassy riverside domes that make Design Centre Chelsea Harbour a landmark.
Sanderson Voyage of Discovery collection - Floreanna printed on 100 per cent cotton satin, £46 per metre, with throw backing and cushion piping in Henna weave, £51 per metre, and Drop Bead Fringe on cushion on the decking, £47 per metre (sandersonuk.com)
At the Paris launches in January, British "big botanicals" were a huge hit with decorators from Europe and the US. These designs have now come home to Chelsea, with a flourish of flowerheads, bursting buds, lush leaves and even whole trees in exquisite detail.
See Woodville at Zoffany, for example, with prints and embroideries. There's an eye-popping pink for peonies that took three months to paint. Dreamier are the soft magnolias printed on to a linen "warp" of lengthwise threads before a blurring "weft" is woven in.
One of the concepts explored by fabric designers is Painterly - watercolours, brush strokes, daubs and blobs are trending in Chelsea for spring this year.
Pleasure Gardens Frost Flower, width 137cm; Big Smile Sky, 140cm, both £70 per metre, 100 per cent printed linen. Sofa, Pleasure Gardens Velvet, 133cm wide, £140 a metre. Cushions, left to right, It's Complicated, Beginning and Passion, all £80 on printed linen, 50cm x 50cm. Desire collection by Jessica Zoob for Romo (romoblack.com)
The super-soft paintings of artist Jessica Zoob are already wall candy for interior designers, who are sure to love the fresh look she has created for Romo's new upmarket Black Edition brand - these are Impressionistic designs, elegant and light. A super-wide linen sheer can fill a wall in one drop, so you can have a deep pattern border along the bottom edge. Extra-wide wallpaper repeats this clever trick, with the prints so detailed they really do look hand-done in layered paint.
Manuel Canovas is reliably tropical and OTT, with trademark cerise and lime in huge embroidered petals, offset by solid blocks of colour. Creation Bauman does big, digitally printed bouquets, and for jungle-style prints at Sanderson, try its Rainforest range.

"Provenance" is another buzzword.
Collections are based on archives, maps and documents. Folie by Cole & Son comes from 18th- and 19th-century French gardens, buildings and stories. Most charming is a confection of picturebook animals wandering in a formal garden, inspired by the fables of Jean de La Fontaine, in pink, chartreuse and lime.
Toiles in Trianon by Canovas tell tales of objets and grand landmarks, plus patterns pastoral and maritime. Even Darwin is here with Sanderson in a Galapagos map.

Ceramics maker Emma Bridgewater brings 30 years of hand-decorated pottery to its first wallpapers and fabrics collection. The firm employs more than 200 people in Stoke. The "dresser" trompe l'oeil wallpaper, painted by founder Emma Bridgewater's artist husband Matthew Rice, is a triumph and three times wider than standard rolls.
