I have a few colors of faux leather and I can't sew anything else until I use them all; so I started!
This time I stitched the seam allowances down with a very thick, decorative thread. It's 100% polyester and shiny. I think it looks like the thread used for topstitching on jeans.
I have a few colors, I am glad I found an use for them.
NOTE: In this picture I did not stitch with the thick thread.
Of course, they (like many other threads) unwind very easily; most of the time I am not a very organized person, but sometimes I realize that some details matter and make your life easier - like this little sticker.
