Whenever I buy a vintage quilt I have my own intake form that I record all the info.that I can glen about each quilt. Purchase date, location, any vendor info, size, the pattern/s, color/s, style of quilting, general condition, if it's dated, etc. I also put each quilt on my design wall and take lots of pictures to show all the visual aspects of the quilt both back and front. It's kind of my own archive system. I have about 50 vintage quilts/ tops now so I'm getting to the point where I really could not keep all that info straight if I did not write it down!
The tag said c 1870 I'd go along with the vendors guesstimation plus/ minus. There are a lot of brown / pink, red, indigo and shirting fabrics that are consistent with that time frame. It's pretty worn and somewhat faded but for all that it's pretty intact!
Every central block (the flower part) is framed in a light strip but then separated by scrappy sashing so it's hard to tell is the blocks were assembled in rows or 4 patch style?!
There certainly is an amazing variety of old calicoes and shirting fabrics in this quilt!
Another interesting thing about the blocks is that they were pieced not appliqued. You can see that clearly in this block where the seams have come apart and there is no foundation fabric underneath. al There are also seams leading off to the corners which you would not do if it was appliqued!
Here's a look at the edge. The front and back are simply folded in at the edge and machine sewn together. Lori called this a 'knife edge'. I had never heard that term before but it is certainly fits!
The back was plan muslin and has some water marks here and there. But for all it's wear and tear it's still a grand old quilt!
