I used some of these types of panels to sew right side (of panel) to wrong of sweatshirt. I would sew along of the the lines on the panel starburst, then I would cut out some of the the middle parts... so you would see the starburst thru the sweatshirt. I think I have a picture of one I did with this particular panel somewhere. let me see if I can find it........ brb
I couldn't find a picture of the finished product but I made some yo-yos out of the leftover fabric and used them in the middle of the circle. Let me know if you want to try this and need more info....Don't know if it will let me copy a picture in comments but I will try.
it won't let me... but I cut close to the stitching lines on the panel and removed the sweatshirt fabric. I can send the photo to you in an email if you wish. :-)
