I have done lots of twin needle stitching. Most of it was in heirloom sewing. When my granddaughter was younger, I made her dozens of cotton knit shirts each year. I did most of that sewing on my serger; but I did not enjoy converting the serger to the cover stitch for hemming the shirts so I used my Bernina with a wide twin needle. I once took a class in which we learned how to turn corners with a twin needle. Although I enjoy using a twin needle in garment sewing, I cannot see myself using a twin needle in quilting.
