Totally agree with not quilting through them. I’m a longarmer and won’t sew through them. The stitching isn’t as good and the one t-shirt that I did quilt through, the stitching ended up coming apart after several washings. Lesson learned. I will stitch around the logos, but not over them. Unless the rubberized logo covers the entire shirt, stitching around them will work just fine. Plus, stitching around it “puffs” it up, making the logo stand out.
