In addition to making custom quilts and t-shirt quilts, I also teach a few quilting classes here and there. Based on that experience, I can say that many quilters have difficulty with making the y-seam. I’ve created a short video showing me completing a y-seam, and I’ve also written a short tutorial (download the y-seam tutorial pdf).

If you feel intimidated by the Y-seam, I hope this helps!
