I have to admit...that block for Nana has a mistake in it according to the original pattern..
The middle block isn't suppose to have the corner tabs on it, suppose to be a solid block but I didn't think I had enough of her fabric left to cut another solid 4 1/2" block so left it. It still turned out ok I think! Ive also made that block many times and don't know why I had such a problem last night!...Maybe watching Big Brother and trying to sew at the same time isn't a good idea?? LOL
