Pants Patterns Compared | Video

Fit instructor Sarah Veblen explains how to evaluate a pants pattern, and what features to look for when choosing a pattern to fit.

Fit instructor Sarah Veblen explains how to evaluate a pants pattern, and what features to look for when choosing a pattern to fit. Through a comparison of several pattern brands and styles, she shows how different the crotch curves can be.

This area of the pattern is one of the most difficult to fit, so starting with a pattern that has a long, J-shaped back crotch curve can facilitate the process of getting a properly fitted pair of pants.

    Once I have fit the Eureka Pants Pattern, how do I use that information (comparing crotch seam lengths, front, back pattern pieces, etc.) to fit an entirely different pant. Is it possible to lay Eureka pattern on top of different one and extend back crotch length, for instance, and get good results?

    This is an excellent question. The best way to use your fitted Eureka pattern (or any other pattern that you fit following the method shown in this video series) is to put it to work as a master pattern. You can restyle the fitted slacks pattern into a wide range of pants designs.
    My suggestion is to examine the pants style you want to make, and adapt the Eureka to reflect its features. Widen or narrow the leg, raise or lower the waistband, add pockets, a fly-front zipper, etc. etc., and make a test garment in muslin.
    Some pants styles might require a slight change in the crotch extension length. The Eureka is a slacks style and therefore doesn't cup under the derriere, the way many contemporary pants, including jeans, are designed to do. In this case, experiment with slightly shortening the extension at the inseam end, until you get the fit and look you want.

    Thank you for this video and my problem is that the back of the pants don't seem to come up to the waist as the front of the pants...Is this a crotch fitting problem? Thank you..Terry
