Hello!! I rescued this chair from the side of the road & I am trying to refinish it. Can anyone help me identify what the groove is that runs along the back of the chair? It's about 1/2 inches wide & 1/4 inches deep. Lots of little holes in it, perhaps from staples or tacks. Is this for decorative tacks? I am trying to make a frame for the back of the seat by hand, but I'm confused what role this little groove plays in the upholstery of this chairback. Any advice is welcome! Thank you
Sorry for the quality of the photos but unfortunately I had to downgraded the quality by a lot in order to meet the upload requirements. I can email higher quality pics if needed.
