DIY Umbrella Sleeve
BeginnerFreeThe source suggests sewing a pattern-free umbrella sleeve from sturdy lightweight fabric, preferably water-repellent. It gives the umbrella length and circumference measurements, a 5 cm allowance for the casing and 1 cm seam allowances, and the main sequence of operations. However, the finished piece dimensions, fold line, and boxed-base construction are not described clearly enough to reproduce without fitting it to your own umbrella.
