So im Super new and this is my first ever try. I did something wrong over all and it didn’t work out like I thought at all so I’m just kind of playing around now.

In the picture you can see there’s a thread right in the middle (that’s going over the thread I would expect there (there’s kind of a hole in the weave is the closest I know how to describe it).
Can someone explain to me how it got there?

Thanks in advance!
