NEXT: My secret to success with snowball corners is to leave the original corner intact and not cut away anything! I take the block to the iron and use the original corner to match my candy corner to. Then I press. Even if I sewed a wonky, curved seam, you will never tell once I press with my corners lined up. Then I still keep that corner, as it adds stability when piecing those blocks together. If the extra bit of thickness worries you, you can trim away the middle layer—the part of the candy that is covered. Trim that layer only to ¼” seam allowance, but keep the original corner of the background fabric.
