I would like to join. I actually have a vintage pattern I've been wanting to make.
I have some fabric with stripes that are about 45 degree angles. There are quite a few panels in this pattern. Would it make sense to cut every other panel upside-down so the finished product makes zig-zags?
My mom always taught me to make sure I cut fabric giong to same direction, but I don't remember why, maybe the way it will look after it is washed? Any help? I think zig zags sound kind of fun.
Some fabric has "nap" which means that it only runs in one direction. Like velvet, when you rub it changes color? You want all your pieces running in the same direction so that when you "pet" your finished garment it all looks the same. Same with corduroy, any fabric with a brushed finish to a lesser degree. Also some fabrics have a pattern that is printed such that it only runs in one direction, like flowers with stems that you wouldn't want to be upside down or something like that. Most patterns have suggested layouts given for "nap" and "without nap".In the case of a gored skirt (long vertical panels) the layout would likely suggest every other panel turned upside down to make the most of the fabric. As long as what you have is an even weave fabric without nap, it sounds like a great candidate for exactly what you are planning.
To echo what Irene said, and based on your description of the fabric, you'll get chevrons which can be quite flattering. If the stripes are very narrow there is no need to match at the seams, you'll still get a great effect. If the stripes are wide you'll need to match each seam when cutting and sewing, can be time consuming but the results can be stunning.
Can you post a photo of your pattern and your fabric? I think we'd be more confident in helping you make your decision with those to look at. You said it was a vintage pattern, is there a date on it? Chevron skirts were popular in the past, I'm kind of vague on dates but I'm thinking early '60s? Probably not the only time they were popular. Hope this helps!
