I came close to changing my mind about doing the triangles along with the blocks when I discovered my first triangle is a known "bear". I persevered anyway, and it didn't turn out to be as hard to make as I had first feared. I'm actually very pleased with how well it turned out.
I didn't add any extra seams; instead, I paper-pieced everything but the central "corn cob", which I appliqued on last. In fact, I believe I followed Anina's directions to the letter, (except I'm pretty sure she didn't specify to catch the excess seam allowance from the upper white triangle next to the applique, in the upper left white triangle seam, then not notice it until it is all put together and you're appliqueing merrily away. This is a more exciting approach, because suddenly you see a raw edge on the right side of the triangle where no raw edge is supposed to be! Panic ensues. I had to remove the top triangular paper-pieced section, then undo the upper left white triangle seam to remove the errant fabric. HOW did I not notice that earlier?) I'm glad this one is done.
