Loving old quilts and blocks

As you know I love old quilts, quilttops, blocks and fabrics. And with the help of my friends in Seattle and the USA I have enough to do a show-and-tell. But there are several blocks and tops still waiting in my cupboard to be finished.

What makes them so interesting?
Well they have something special, or mostly smell special ; ). But I love to finish those unfinished projects. Even though experts says that you have to leave them as you found them. Well I don't.
I love to turn them into new quilts.

Dating the fabric
The problem is that I often don"t know anything about the top or blocks.

So I have to figure out with my books and make a guess as good as I can.
 
 The nine-patch quilt

I sew the 12 blocks (each block was made of two nine patches and two solid blocks) together.

These blocks got my attention for some reason.  There is something strange about these blocks.

Not the pattern because that is pretty common. But then I thought I think the blocks are made in several periods. Maybe even made by two different persons.
If I look at the hand sewing the small blocks have smaller stiches then the big blocks.

The brown fabric seems to be older, coming from the period 1860 - 1890, the big blocks seems to be later 1910 - 1930s. Isn't that interesting.

Is there an quilters (expert) in the Netherlands who wants to help me to learn more about my quilttops and blocks?  And are there more quilters who just like me love to work with old blocks or tops?
