Paper piecing, part two
The blocks I am making have three parts that are pieced separately and then sewn together. After you have finished sewing the separate pieces for your block, and pressed them, it is time to trim them. Put your finished block piece fabric-side down on your cutting table and trim the edges. When you line up your ruler, line it up with the STITCHING line, give your self a 1/4" margin and trim whatever sticks out. I do this instead of lining up my ruler with the outside line of the block, because sometimes I discover that the line has become distorted from copying, and I want to make sure I have the correct seam allowance.
If you don't get your bearings on where you are in the block, you may sew the wrong edges together and end up with something like this... Ooops!
OK, now line up your pieces (correctly!) and sew a careful 1/4" seam.
If you have trimmed and sewn accurately (that is easy, since you are sewing on lines!) when you turn it over you will see that your stitching line is right over the line on the bottom side.
Ta Da! Now your blocks are all complete and you can finish your quilt top!
