This was a very straightforward design that was very enjoyable to crochet. My only grrizzle, which I have noted before is that this book puts a space between triple and treble (tr tr) and my mind ignores what appears to be a typo/double up. I prefer triple treble to be noted as trtr with no space.
It can be found in “75 Crocheted Floral Blocks” by Betty Barnden on page 68. This is the tenth square from this book. My challenge is to crochet 50 different Granny Squares and as part of this challenge, to choose 10 squares from each book. So, now to find one last book that will provide my last 10 squares.
