I have found out that the favorite color of the 5 year old is purple and Cheri says that Adalynn Grace loves pink. What type of square should I use between the Sun Bonnet Sue blocks. I thought about using a smaller square of a 30's repro fabric in purple with deep purple triangles on all sides of the square placing the center square on point. Then use the dark purple as a border. The I would repeat the same proceedure with the pink. Would love to have your thoughts on this.
