Thanks for all of your suggestions. I have plenty of the Robert Morris fabric and will make sure I buy enough of the off white in case I need to add another row of the on point squares or decide to add a solid border to add to the width and length. I now thought of something else. Most of the Robert Morris fabric is directional so I will be cutting on the bias. Will it be ok to cut the off white squares on straight of grain or will I have to cut those on the bias too?
