I have 2 series of books I go back to constantly. Around the Block by Judy Hopkins. 2 other books in her series. They have rotary cutting instructions for over 200 traditional blocks in each book in multiple sizes. The other series is Block Magic and Block Magic Too by Nancy Johnson Srebro. Again, they are rotary cut blocks in multiple sizes, but the blocks are pictorial, like people, vehicles, flowers, bears, school and other buildings, etc. Plus she has quilt patterns in the back.
