Since my piping was white, I thought the wider piping would make it stand out better, the mini just dissappeared with this fabric! I cheat on my corners….. I sew to the seam allownce at the corner, then pick it up, needle too, and turn everything leaving a “pucker” in the piping at the corner and sew down the other side. There are a few skipped stitches at the corner. When I sew my back piece onto my collar I sew to the corner, diagonal across those 2-3 skipped corner stitches (catch the piping header, but be careful not to catch your pucker) and straight down the other side. I don’t really know the correct way to do this, but this has always worked for me!_________________
