This cool colorful phone case has two sides – bright ultramarine and emerald and is suitable for iPhones and most smartphones. To make it you’ll need a tech case template, a pen, scissors, a needle, paper clips, oilcloth in emerald and ultramarine, thread bobbin in emerald, sew-on snap and a silver prong stud. Cut out each side of the tech case template. Choose which color you’d like on the back and which you’d like on the front. There is enough of each color to choose either the blue or green for either side. Trace the template on the backside of the oil cloth fabric. Cut the fabric along the lines you’ve traced. Read the rest of the tutorial here and finish the case.
