There are actually quite a few. Like Apis said Michaels. There's also Canada Crafts which has a huuuuuuuuuuge warehouse of stuff out in Burnaby near the SilverCity and also a 2 story biiiiig space downtown as well. I think they probably have other locations and they have lots of stuff like Michaels. Same thing can be said of Loomis. I personally haven't shopped at Lewiscraft in over 3 years....

Other than that there are typically smaller more specialized stores depending on the craft, as well as art specialty stores.
