I've been slowly but surely working on a bed quilt that I've been updating from time to time. I'm at the point of joining 9-patch blocks to snowball blocks. When I do this, I'm joining an angled seam to a straight seam so it is a little more difficult to make them match accurately; however, there is a simple trick. Let's see what that is....
Use a pin to match the points of the seam 1/4" down from the raw edge. Be sure you DO NOT measure 1/4" along the angled seam as this will not be accurate - it needs to be measured straight in (perpendicular) from the raw edge.
My close-up photo shows where the pin goes through both sections. The angled seam is on top, and the straight seam is visible behind it. The pin is going through both seams exactly where it will be sewn (1/4" from the edge).

The next photo shows where you stitch the seam. You can see the pin pierces the fabric exactly in line where the seam will be sewn (seam line is indicated with dotted line). When stitching the seam, sew right up to the pin before removing it. Don't sew over the pin just in case you hit it - this can damage your machine, not to mention break the needle.

After the seam is sewn, press the allowance to one side. Then open it up to see perfect points.

Simple but effective.... give it a try!

Thank you Barbara!
Great way to show how to get those points to match
