I better start this post with a disclaimer that this is no way a polished full tutorial. These instructions began as an add-on to my review of the In the Folds Peplum Top, demonstrating how I achieved a mitred v-neck using a bias facing that was not cut to pattern dimensions (ie, just one long strip). But as the review ended up being so long, I separated it into two posts, to save endless scrolling and allow easier access if you want to use this technique on another project.
If you want to know why I think it’s a good idea to cut your own strips of bias tape and apply them as you sew, check out my review. If you want to know how to do it, keep reading!
