I'm not a lefty but my Dear Aunt was. She always complained because things were made for right handed people. Not any more, we have lots of things for left handed people. Even a very nice quilt teacher at the Missouri Star Quilt Co. Just take a look she's good and seems to be a really nice person.

P.S. Leave the block alone, I thought it was supposed to be that way since a table setting has the spoon on the right side.
