Jian / Jian

"Jian" is a convenient type of line tube. When people finish needlework, they often put the thrum in the lines of tube, and next time they use it they have to arduously take the thrum and the line clung apart.To make this easier, I designed a line tube with a slot, when people wind the end of line on the tube, they can put the thrum in the slot, so next time they could easily find the thrum and take it out
