I don’t remember ever crocheting a square from the outside in before, although I have done this many times in knitting. I really enjoyed the change and it really kept me interested when I was constructing the flowers in what I considered to be upside down.
This is another single colour square to balance out the colours so I enjoyed not having to sew in multiple beginning and ending yarns. It can be found in “75 Crocheted Floral Blocks” by Betty Barnden on page 91
