For anyone still having a hard time getting a 16 1/2" block and having trouble getting a perfect 1/4" seam... I took a slightly different approach to getting the 1/4" seam right and it seems to be working so far.
Rather than testing the accuracy of the 1/4" seam in the more conventional way, I took one of the paper templates, cut on the line for the seam allowance and then used that as my test under the machine. I placed the needle on the paper seam line, placed a "purple thang" to the right butted up against the template, then stitched on the seam line of the paper template. If stitching stayed on the stitching line, then my purple thang was properly aligned and because I used the actual template, I knew I had a perfect 1/4" seam. Instead of the purple thang, you can use post-its or tape.
While I have not put all the blocks together to finalize the star block, ALL of my points are aligning perfectly so far.
I finished the block. Here is the sample using the template as a guide for the 1/4" seam described above.
In addition to using the template as a guide to determine the perfect ¼”, I followed Sue Garman’s instruction on putting the individual blocks together and pulled paper off the back of those. However, I did not pull paper off the back of the blocks that did not require further assembly after the paper piecing was done (the middle block and the four corner blocks). When it was time to actually sew the blocks together in vertical rows, I used Wonder Clips to “pin” NOT the seam where I was going to sew the two blocks together, but on either side to keep the two blocks together and straight. I used pins where needed along the side where the blocks were to be sewn together and I made sure the seams kissed perfectly, then I sewed a basting stitch across (3.5 stitch length), on the seam line of the paper template, took off the Wonder Clips, checked to make sure everything looked good; if it did, I sewed over the same seam with a 2.0 stitch length. I took the papers off and pressed my seams. All of my vertical rows measure exactly 16 ½”. This worked for me much easier than with my first sample (Christmas table topper):
With the first sample, my block finished at 16" rather than 16 1/2". Since I paper-pieced and sewed exactly on the seams, I concluded that my problem was not having a perfect 1/4" seam. Using the paper template to set the 1/4" seam on my machine made the whole process a lot easier. Now I'm ready to move on to making the actual halo medallion block! My samples were all made with scraps. Here's my fabric selection for the BOM:
