I made a smartphone shoulder bag with Kogin-zashi embroidery on linen fabric. Far-Eastern Tsumugi is used for the inside, and simple embroidery is on the back. To prevent the shape from collapsing, I sandwiched quilt batting and interfacing. The shoulder strap is 1.5mm thick, so it cannot hold heavy items. This is made by an amateur using a home sewing machine. Please understand that the finish is not perfect, such as some slack in the lining. ▪️Size Width: Approximately 14.5cm Length: Approximately 22.5cm The shoulder strap is 9mm wide and can be adjusted up to 135cm long. ▪️Materials Linen (Olympus Embroidery Cloth No. 3500 Linen Cross), Cotton (Tsukiya Kogin thread, DMC embroidery thread, Far-Eastern Tsumugi), Polyester (sewing thread, quilt batting), Polyester, Nylon (interfacing), Polyacetal (snap button), Synthetic leather (strap), Metal (D-ring, hook, adjuster)
