Lovely wrist warmers! I like how the rib widens out every now and then, and the color works perfectly, something that doesn't always happen when you've got several things going at once.
Did you say there's a mistake somewhere? Don't see it, can't find it, not even looking for it, so don't worry about it.
If someone can't see it driving by in a car at a slow 30 mph while you're dangling your wrist warmer out the window, then you're good! (That's my modern take on the old saying about spotting errors from the back of a running horse . . . or however that went).
