I was also tempted to make some string blocks. This is a picture of the 10 blocks I made today.
These blocks are made using used dryer sheets as foundations--6" x 8 1/2". I understand why everyone has started making these--they are incredibly fast and easy to make. Today while taking to my Mom on the phone, I made two from start to finish--including the trimming. They are also "feel good" blocks because you realize that every block you make you are decreasing your pile of useless strings. Less strings means you can free up space in those totes and drawers that we all have bulging with fabric.
I like how Patti set her blocks together and I am thinking about doing something similar. I think she really made her blocks pop with the use of the narrow sashing and cornerstone between the four blocks contrasting against the wider sashing and cornerstones outside the group of four blocks. Excellent idea!
