I made this block as a part of a sampler (called a "triple rail" in my pattern). Indeed, mine looks like a swastika. I noticed it right away. I'm not sure there is an answer to this problem except to simply stop making the block. But in my mind it's no different from turning regular speech into dirty speech the way a lot of people do when they think they're being funny. When someone does that, I always tell them to keep their mind out of the gutter. I think the same is true if someone sees a swastika in this block. It's not a swastika. The block contains much more than that.
