Thank you so much to each and every one of you who gave me valuable suggestions in my last post. So the majority of the people gave a thumbs up for a common turquoise border.
My confusion was that usually the granny square works I have seen follow a colour scheme which is exactly the opposite of what I am trying to do. That is vibrant colours with a subtle border. My border is more vibrant than all the colours inside. But I am loving it more and more now. Have made 24. I am planning to make 80 or maybe 100. Lets see!!
Thanks again for your comments. Really appreciate it!! Have a happy weekend!!
