I have returned to “100 Bright and Colourful Granny Squares to Mix and Match” by Leonie Morgan and my 50 granny squares challenge.
This block is called Flame Flower and is on page 44. The flower is crocheted first then the square is crocheted behind it and the petals are attached to the background square in the final row.
The clever thing about this book is that all of the squares finish at the same size. In this way they can be readily joined together without any modifications.
