The letters are cute. haven’t tried to adhere them yet. However I’m missing the letter “G”. I received two letter “Q’s” instead. BummerLetters look great- adhesion needs improvementSuch cute patches but missing letter LReally cute letters but I’m missing the C which is a main letter I need so I had to order another packageVery hard to get to stick with iron. Had to sew and glueSeveral letters missing, including the one I needed most :( quality not quite as good as from the place I normally order but Price was good. Didn’t try using any since there are so many missing so I can’t speak to how well they adhere.These are good size. They did not stick on their own. I added some adhesive spray on the and that worked fine. I liked it and I get compliments every time I wear my shirt.Very nice came quickly but!!!! letters missing which is really annoying, as they weren’t that cheap!!Ordered these letters for my daughters leaving school day to sow in shirt however there was no letter R which she neededI am happy with these letters. I am not sure about the adhesive, as I haven't used the letters yet. On that note, I plan to sew them in any way. But the colour and quality are very good. The size is perfect as well.Update: Oct 22, 2022. I have change my review to four stars...here is why.I have put the letters on a jacket and the adhesive isn’t great. I am a seamstress, so for me this wasn't a deal breaker, but if you are not a sewer or don’t have access to a sewing machine, this will be an issue for you.I was very excited about this product, but some of the letters were dirty, the back had some of the adhesive peeling off, and when we ironed it on, some fell right off or peeled off the edges. I ended up having to stitch around each letter.Cute product, not very easy to iron on. Someone did suggest I use a glue gun instead.
