Make patterns. According to the size of cotton slippers, cardboard can be cut into patterns, which is the standard for making soles and uppers in the future.
Prepare materials. Clean the jeans you don't wear and make them into cloth with paste. Three layers of jeans are one layer of fabric, soles need three layers of fabric, and cotton slipper uppers need two layers of jeans and one layer of uppers (outermost layer). Cowboys can be used as the outermost layer, or other stronger printed fabrics can be used.
It doesn't matter if the denim of the first layer of cotton slippers is broken, just stick it flat. Anyway, the innermost layer can't be seen. Then make the second and third layers of cotton slippers, and pay attention to the smoothness and adhesion of the folds.
Make cotton slipper uppers first, and then close the soles. This is not an easy job because the foundation is relatively thick. The stitches must be flat and symmetrical, so that the soles are beautiful and comfortable to wear. Hand rubbing hemp rope can be used to hold the sole, because it is strong and durable, so cotton slippers are not easy to break. Of course, you can also use chemical fiber rope, and choose according to your personal preference.
Wearing shoes means sewing the finished upper and sole together. Then a beautiful cotton slipper is made.
