Nail tech Melissa Guyer of Cedar Rapids, Iowa, came up with the perfect way to advertise her work and start a conversation with potential clients. “I decided to make a collage of all my most recent and favorite work,” she says. Guyer turned to the Photo Grid app to make a collage of her favorite nail images. She then ordered her case through Casetify’s custom option. “There are usually coupons on the internet for first-time orders. It was normally $40 but I saved $10 with the coupon. Best advertising tool ever!” Follow Guyer on Instagram @11polished11 to see more of her work.
