Here's the picture of how I use the T-Pins around the hoop to make sure it stays taunt while stitching. I hope this makes it clearer to understand.
What a great addition to a hoodie to liven it up! How did you get your fine points so sharp without any puckers? Everything I do on sweatshirt fabric ends up with some puckering at the points.
Not sure what went right with this, LOL, I hooped a medium weight cut away and fastened the sides in the hoop with T-Pins so it would stay taunt. I then hooped the the shirt on it. I'll try to take a picture of how the T-Pins are arranged.
