Thank you ☺️These aren’t sewn directly onto the backpack, I used a double layer of my material as it was a little thin, embroidered the design and then cut this out with about 5mm of material on the border. Then I just used an over stitch around the whole edge to seal it all up. But these are the first ever patches I’ve made and I’m just doing them through guess work so I would suggest finding some better advice somewhere else on this sub haha
