Well I finally did it! I finished a block and it is a perfect 12 inch finished block

16 half square triangles....back to thangles! Maybe this head cold condition has something to do with it.....or maybe that the trip to the Doctor with my 83 year old mother to learn she needs gall bladder surgery made the day a stressful one. Any suggestions? I have enough to make a second block....this one is beautiful....just missing a half inch!
