So is sewing curved seams hard? Well, not really- it's just like sewing in a sleeve! I practiced a method with pins and without pins and I found using pins to be both faster and more accurate. I am really happy with these blocks.
The quilting wasn't too difficult, though there was a lot of traveling involved. On the spiral block I wobbled really badly at one point, so I'm a little annoyed about that- but I absolutely LOVE the design. It reminds me of Celtic Bubbles, that I use quite a bit. For that block, because there is an open string end in the middle of the block, I actually had to bury my threads. Since these blocks will be cut and sewn together later, I have just been sewing right off the edge as a shortcut :)
Someone on the Building Blocks facebook had a brilliant idea to use a computer program to put together images to share our quilt progress. So cool! This is what I've done so far, and what is yet to come!
