Wow, this is so cool! Love the way you used sewing to tell a story about sewing. I enjoyed the way I could get little extra details and then return to the main story, it kind of felt like being at a museum and reading some of the extra infomation. But the coolest moments for me were trying to open up and not being able to, and then finally doing it anyways in the end, even though it's scary. It was an interesting experience either way, but it hit me quite a bit harder than I expected, as I can see how I have my own fears and worries about things like this and how difficult it is to open up about it. Great work!
I am also guessing that your first language isn't English (going by the Spanish comments), as I noticed some grammar/spelling mistakes, but even then it was just a few, and the meaning was perfectly understandable. So well done on writing something in a different language!
