I'm doing a block called Windows which I got from Quilters Cache
an excellent source by the way!
I can't find a picture of it, but it's a very simple block with four triangles in the middle making a square and then a border....so there I go four triangles joined, and pressed. First border piece in hand and....o-oh...there's no way this is going to fit it's far too small! To cut a long story short....the triangles should have been cut from 5.25" squares, but my square was 6"! Duh....so I must have totally mismeasured all the squares that I made my triangles from!

I haven't got enough fabric to cut them all again, so I'm going to have to trim them up to the right size...good thing I have plenty of time!!
