Hello Sewing Peeps:
I decided to have a look at the Kwik Sew 3807 pattern this evening, to compare it against my other pants sloper and to see how I can realize the gains of the sloper in constructing the new denim leggings. Of course, comparing a wide leg, 4-piece pant against a narrow, 2-piece pant is not exactly intuitive. I mean, not the first time you try to do it, at any rate.
Intriguingly, as you sewists probably know, the 2-piece pattern is like the front and back leg pieces attached at the centre. Cool, yes? But I'm having difficulty determining whether I need to decrease the crotch length because the tops of the pieces (i.e. the waistlines) don't exactly align.
Here's what I propose to do: I'm going to diminish crotch length by 1.5 inches (the same amount I did on the sloper) because my only other experience of a stretch fabric pant from Kwik Sew (the yoga pants pattern) was also too long in the crotch - much as the sloper pattern was. Perhaps my crotch length is generally shorter than those in "average" patterns (at least Kwik Sew or the 2 patterns I've already tried), because a) I am proportionately petite (rather than simply short) and/or b) that's just my shape.
In terms of crotch depth (the actual arc of the curves of the crotch lines on the pattern pieces), they seem fairly consistent with the post-alteration ones of my sloper. It's hard to tell, because all the lines don't really match up, but if I just look at arc (disassociated from everything else), that's what I see.
Does anyone have any secrets when it comes to transferring the relevant sloper shapes from one pattern to another - especially when the patterns (while of the same garment type) are different in most other ways?
Thank you all for any info you can provide.
