The needle is puncturing the fabric, not poking in between the threads. My stitches are actually distorting the fabric. Sometimes this is caused by a dull needle. Today, I know it is the size. I forgot to adjust for this bridesmaid dress.
|Here's a little clearer view. Since the needle is poking the thread, rather than going through the weave, it pulls the threads, leaving those lines. They are not repairable. They are permanent.|
|Luckily, they are not visible from a distance. The client will not know my mistake. Whew! And I caught the trouble early enough that it only affects a small part of this hem job. Sometimes when you have done a job like this so many times, you get complacent. Avoid that at all cost, so your quality remains its best.|
