Leather is great and combines well with jeans and many other outfits, that why leather shoes and accessories are amazing. To make this simple leather bag you’ll need leather, leather cording for strap, thread, linen or nylon, magnetic snap, 2 needles, pricking iron or a stitching awl, mallet, rubber or wooden hammer, a hole punch, glue. Cut a rectangle and make stitching holes along the long side for the side seams using a pricking iron, stitch punch or awl, about 0.5 cm from the side. Cut a piece of thread about 5 times the length of the seam you’re going to sew. Thread a needle at each end and ‘lock the needles’ as is very well explained here.
