How to adjust a pattern to a sloper.

jeanvand | Posted in Patterns on

I have make myself a sloper and am trying to adjust a pattern to fit it.  The problem I’m having is the blouse pattern is so off from the sloper.  The pattern is one with “all- sizes- included”.  I have a very petite neck-to-waist shape and when laying the sloper atop the pattern, matching the back center neckline and center back waistline, the shoulder slope is way off.  I’m at a loss as to what to do.

    Adjusting pattern to sloper

    Karen Howland contributed two excellent articles in Threads magazine regarding matching a pattern to your personal sloper.  If you haven't already seen these articles, they can be found in issues No. 79 - P48-52 and No. 83 - P61-65.  Hope this helps.

      Hi I was wondering if you have a copy of the Cut to Fit book by Karen Howland.

      I am trying to locate a copy with no success

      Tried this

      Cut To Fit: How to Make Clothes that Fit

      I got the author Karen Howland to write a blurb for me:

      From: [email protected]

      After many frustrating experiences trying to fit commercial patterns to my

      clients, I found a much easier way to fit: make the pattern to fit in the

      first place. This is easier than it sounds, and is really rather fun.

      Patternmaking begins with a sloper, a basic fitting pattern that includes

      wearing ease. The sloper represents the needed fit. By designing from this

      sloper, the fit is built into the pattern.

      Cut to the Fit explains in a step-by-step format how to draft skirt, bodice,

      and sleeve slopers. Drafting pants is also covered.

      To make the math of patternmaking easier, I also have a 30" metal ruler that

      includes a half scale and a quarter scale. No dividing numbers necessary.

      Cut to the Fit costs $39.99 plus 4.00 shipping. The ruler is $14.99 plus

      $3.00 shipping when ordered separately, but the book and ruler together are

      $49.99 plus 6.00 postage. Illinois residents please add sales tax to the

      before shipping price. Send check or money order to:

        Hi Scheri - sorry I don't have a copy of Cut to the Fit, but I do have a copy of Karen Howland's "Pant Fitting Made Easy".

    The whole point of using a good fitting sloper pattern is to correct the other patterns.  If the sloper fits properly, you would go with the shoulder line on the sloper and not the pattern.  The pattern may well have ease added that is part of the design. A muslin would help you here.  And remember a muslin does not have to be the full garment.  If I am trying to figure out a neck line I may just cut the pattern from the bust line up.
