3538 MINI-MONSTER PRISM |
We've had our eye on this macho needle kit. It includes (7) steel needles: (1) 1-3/4" for leather, (1) 1-3/4" for carpet, (1) 2-1/4" for sails, (2) 3" needles, one for packing and one for canvas, and (2) 2-1/8" dia curved needles, one for mattresses and one for lampshades. All right. So maybe you can use the lampshade needle to sew up softballs. May we suggest you stick these on one of our magnets, so you always know where they are?
