Since its humble beginnings in a Fitzroy garage in 2007, Redbubble has grown to be one of the largest online marketplaces for art.

Today more than 250,000 artists from across the world sell their work on Redbubble, which can be printed to order on everything from iPhone cases to giant canvasses.

This Saturday and Sunday, the Redbubble team will turn the spotlight on its hometown talent for ART+MEL, an interactive exhibition showcasing work from more than 100 Melbourne artists.

Building on similar events it has held across the world – including at South by Southwest – CEO Martin Hosking says the group wanted to introduce Melburnians to some of the city’s lesser-known talent.

ART+MEL curator Ana Kresina says the goal was to exhibit as many Melbourne artists as possible, across the two spaces in Federation Square and Rutledge Lane.

Federation Square will host a bedroom gallery with works printed on doonas, throw pillows and the like.

There will also be pieces from more than 100 Melbourne artists displayed in a floating gallery, including a live installation by Justine McAllister. McAllister, who joined Redbubble a few months ago, will invite the public to help her fill in giant paint-by-numbers versions of her work. If you need caffeine with your art, there will also be free coffee from Code Black.

Over at Rutledge Lane, artists Kaitlin Beckett and Matthew Dunn will be creating a mural live from 10am to 6pm on both days. Visitors are encouraged to join in and can add their own stencilled piece to the iconic laneway’s walls.

Things will wrap up with a free afterparty from 6pm on Sunday at 1000 Pound Bend. All are welcome to come and celebrate the artists and enjoy free drinks for the first hour.

ART + MEL by Redbubble runs from Saturday November 29 to Sunday November 30 from 10am to 6pm daily at Federation Square and Rutledge Lane in Melbourne’s CBD.
