How Do I Save This Shirt This is the shirt I purchased when I was heavier:



I was able to slim the sides.

Unfortunately, fixing the shoulders was a train-wreck (now I've learned the hard way: I need to take-in the shoulders)

When I tried to sew along the thread seams, it was crooked and I couldn't put on the shirt. However, when I tried removing the threads, it made a nice hole in the shoulder area.

How to darn this hole so that it is not noticeable?
It's unlikely that you'll be able to disguise the holes in any way that's not noticeable; instead, I would recommend looking into the Japanese process "sashiko," a mending process made deliberately visible. Based on your other questions, you are quite new to sewing and embroidery, so you may wish to start with a more simple pattern like the one shown on the bottom; with practice, a wide range of more complex patterns exist that you can use in the future.



A wide range of online tutorials exist to get you started, frequently focusing on a diamond or square pattern similar to the bottom example; the repair will be solid and should help prevent further damage to the area, and will make your shirt uniquely your own.
