Some of the Straight needles I have made... pieces of craft store wooden dowels, cut to length, sharpened in a pencil sharpener, sanded smooth, with beads glued on. The smaller diameters on the right started out as bamboo skewers, sanded smooth, with beads glued on. All were rubbed with wax paper for a natural finish. As you can see, the needles on the left have craft store small spools for heads, all the others use beads from thrift store costume jewelry. I have been selling these, and giving them to people whom I have taught basic knitting.
