Me too! It blew my mind that it's really all the same block, just one pattern, and you just turn the block in different directions. I'm sure that's not uncommon, but since this was my first quilt, it was a bit surprise to me. LOL
I started machine quilting yesterday, after the advice I got here. Wow, that's hard to get that big quilt into my little sewing machine! I had to change my strategy. At first, I was planning to quilt inside each seam by a quarter-inch. So I started with one of the squares of a central nine-patch.... but because it's a square, that meant that I had to rotate the entire quilt by 90 degrees THREE times. Yikes! I couldn't imagine doing that for every single seam in the quilt.
I ripped out that seam and decided I would follow the horizontal, vertical, and diagonal lines from edge to edge of the quilt (but not the border). I did one horizontal, one vertical, and then decided that was enough for one day.
