I love needleturn.... where the key is tiny little stitches done very neat that don't show up.
The question for me really is how to get the piece ready to be sewn to the background, and there are so many methods available. I use a combination of different techniques... freezer paper on top, freezer paper on the bottom, no freezer paper, lines drawn on the background, etc, etc, etc.
I can't wait to see the different methods everyone uses for each block.
