This week's new events

Welsh National Sheepdog Trials , Montgomery Jaunty whistling. Gates. Low-slung dogs with their tongues out. These are the component parts of rural Mid Wales' equivalent of football's World Cup: a celebration of absurdly well-trained working dogs and nerveless handlers, who'll be ushering sheep around courses with pinpoint accuracy. With the One Man And His Dog TV programme reduced to niche World's Strongest Man-style one-off broadcasts, it's a rare chance to see some of the best practitioners in action – live. Come-bye, come-bye; that'll do. Henfron, Llandyssil, Thu to 21 Jul Stuart Goodwin Cakebook Britain , Gateshead Subtitled The People's Picnic, this event offers the rather unusual opportunity to see the UK's most famous landmarks rendered in sponge, cream and icing. Cakes of iconic sites such as Nelson's Column, Stonehenge and the white cliffs of Dover will form an edible 100-square-metre map, which hungry sugar fans may try to dive into with their mouths open. Fortunately, there are other foodstuffs available on the day to help prevent this, with local producers selling their wares, plus cookery lessons for kids. Saltwell Park, Sun Iain Aitch Art Couture Painswick , nr Stroud Catwalk shows and celebrity stylists are the last thing you'd expect in a quiet Cotswold village best known for its yew trees and antique shops, but this quirky fashion fiesta sees Painswick awash with sartorial invention. Outfits are made of everything from brollies to bath plugs, stalls and street thespians abound, and Keith Allen and Dawn Harper compere. Yet this open-to-all design contest isn't about fame; entrants range from professionals to art students, and this year include a nursery-schooler and a nonagenarian. A new Body Art category will get heads turning, as will Toffee, the miniature-donkey-turned-model. Who needs Milan and Paris?
