I've made several mug rugs for swaps and haven't done a pocket...is it for spoon?
I don't see how it matters which side the pocket is on, please don't do it over, it looks great! I love it.
BTW, I'm a lefty as well, I've been asked how it affects my knitting, cross stitching and quilting...I don't see how it has, it all looks the same in the end.
