For more than 100 years, the family at Guiry’s has helped customers enliven interior spaces with a continually expanding selection of paint, wallpaper, furniture items, and art supplies. Specialty paints include textured gallons by Ralph Lauren, which swathe rooms in tones and finishes borrowed from natural suede or river rock ($39.99). After covering studio spaces with hues that are conducive to creativity, patrons may continue coating stretched canvases ($2.35+) with brushes ($2.39+), oils ($4.06+), and acrylics ($2.66+). Guiry’s also stocks children’s art kits ($14.96) and customizable Munnyworld dolls, which sport blank expressions until children unveil their individual personalities via creative brushstrokes or hours of shouting.
