Building a miniature ship inside a bottle is impressive, but not as impressive as forging a giant glass shell around the outside of an aircraft carrier. One-up ordinary hobbyists with today's Groupon: for $25, you get $50 worth of fine fabrics and accessories at Marshall Fabrics on 63 Avenue.

Patrons of Marshall Fabrics stitch, seam, and baste thousands of popular and hard-to-find wholesale fabrics from the shop's inventory. At-home tailors can create custom garb to reward favourite grandchildren and maze-mastering lab rats from Melton wool ($19.99+/metre) and patterned or plain polar fleece ($8.99+/metre). The knowledgeable staff helps customers navigate the shelves, which are stocked with fabrics for both clothing and home decor, as well as distinctive fabrics such as native prints ($9.99+/metre) and corduroy ($9.99+/metre). Patrons can keep sweaters from jumping off bodies in feats of rebellion thanks to zippers ($0.75/metre) and a kaleidoscopic assortment of buttons ($2.99+). This Groupon may also be used toward soft cottons, fine nylons, and argyle sections on Marshall's half-off clearance wall.
