Hey Kelly finished my blocks for you and really enjoyed making them. I used a lot of Fresh Cut material since I knew you liked that line. I love the quilt these blocks make up from your example picture and can't wait to see yours finished. I mail these out 2 days ago so they should be arriving soon.
To answer your question, my favorite tool is all the multiple size rulers and templates I have. When you have the exact size what a pattern calls for it makes it so much easier and all your block should be uniform and then go together much easier.
