Nice, you have a wide mix of blues much like me.
Keep plugging along...you can do it!!
I used a big (11x17) piece of paper to sew all of my strips to, and then cut it down into 3.5" blocks. For me it was less frustrating to do SOOOO many little pieces!
Your blocks are lovely. Strings are slow going for me compared to some, but they were worth persevering. They are so darned cute.
You have a nice variety of blue fabrics. I'm wondering - you precut your strings before sewing them to the papers?
