Yes, PegD... that is it... well I must be going colourblind... have recently had my eyes tested too.... a couple of times when I was in a quilt shop looking at black fabric, the fabric looked royal.. I told the optician this but he didn't know why.... but said my eyes are OK... thank you so much and thank you to you all.... I am rapt.. I bookmarked it before I wrote this in case it disappeared on me again. !!!!!! You are all so clever....isn't it a pretty block... I just love it and am dying to try it... got my hands full making a black, white and red quilt... queen size... just on the last of the blocks now but maybe it has something to do with seeing so much black lately...
