  • Needle size for leather

    Hi All
    Will be embroidering a couple of leather jackets and am wondering what size needle is best for this? I've only got one shot at this and don't want to mess them up!
    Many thanx.

    You should re-evaluate that job. Short run specialty has no room for error. So if
    you mess up. You are paying for that Jacket. Not worth the risk.

    Too many variables to advise. Needle is just the beginning. Hoop burn ect...

      I agree with the above. A patch sewn on at the edge is always better on leather in my opinion. Density issues, punch out of the design, etc etc etc.

        75/11 ball point. Use stabilizer. Column density no less than .40. Buy some leather scraps to practice on. For hoop burn protection or to hold hard to hoop items wrap them in Coban tape found in most drug stores.

          stitching on leather Tajima notes

          STITCHING LEATHER
          Stitching an embroidery design on leather certainly can offer an embroiderer some
          challenges but in reality, it really is not that difficult. As in any embroidery work,
          having a good understanding of embroidery basics goes a long way in creating a
          quality stitchout.
          When stitching on leather, the goal will be to 1) punch as few holes as possible
          2) make these holes as small as possible and 3) space the holes as far apart as you can.
          Needle punctures in leather that are too close together, will create a series of perforations
          resulting in a stitchout which can literally be lifted off the leather .... leaving a large hole where the design once was.
          Often, the largest variable in stitching leather will be the leather itself. The type, quality and thickness will dictate
          your specific stitching requirements but in general when working with leather, consider these points:
          [ Use a quality design digitized or edited specifically for leather. A poor design can cause havoc with the
          leather and add excessive demands on the embroidery machine.
          [ If a design was not digitized specifically for leather, reduce the stitch density as much as possible. Amount
          of reduction will vary with the density of the original design but generally 10 - 30 % will be the target.
          [ Remove or lengthen short stitches. In most cases, stitch length should be 3mm or a bit longer. If it becomes
          necessary to use s slightly shorter stitches, do not concentrate many of these shorter stitches in one area.
          [ A target minimum stitch length of 4 mm for fill stitches is desirable. Depending on the design, size of needle
          and the leather itself, slightly shorter fill stitch lengths may work [3mm should be an absolute minimum]
          [ Delete or minimize underlay stitching. With most leather, little or no underlay stitches are required.
          Remember, when stitching leather the goal is to produce as few holes as possible.
          [ Ideally, column [satin] stitches should be at least 4mm in width. This along with reduced stitch density will
          insure that the leather is not perforated to the point that the design can be torn from the material.
          [ Size and type of needle used will vary depending on the leather but always use the smallest needle
          possible [e.g. on soft light leather, a regular 70/10 sharp works well, use larger needles only when needed].
          [ Slow the machines stitching speed down. Friction is created between the needle and leather during the
          stitching process and lowering the machine speed will help reduce this friction.
          [ Applying a drop of thread lubricant like Sew-Smooth, Sewer’s Aid, etc. to the needle[s] will also help
          reduce friction when stitching leather.
          [ When hooping, do not attempt to “stretch” the leather. It should be reasonably taunt and smooth in the
          hoop but never stretched.
          [ With regular hoops avoid having them too tight, wrap the inner hoop with strips of stabilizer or athletic tape,
          hoop leather just before you are ready to stitch and remove hoops immediately after stitching.
          [ To reduce hoop marks, try using something other than traditional hoops. Systems like fast frames,
          clamping frames, etc can be an effective alternative.
          [ Leather in itself is very stable so often the use of a stabilizer is not a necessity. However, when stitching
          leather most embroiderer’s will use a tear-away [if for no other reason than piece of mind].
          [ Test stitch your design on scraps of similar material before attempting the real thing. Thrift stores or
          upholstery shops are often a good place to pick up leather.
          [ PRAY ..... a lot. Not because leather is difficult to stitch on but because mistakes often mean that the
          damage is permanent and the item is ruined.
          Use the above information as a guide only. Depending on the leather itself, the item being stitched, the machine
          used, the embroiderer’s experience or personal preference, complexities of the design, etc. .... variations of the
          above tips may become necessary.
