When I start a new project, particularly one I have never tried before, I spend some time getting acquainted. Reading the instructions, looking at the colors,......
Then I spend some time visiting my fabric and auditioning until I find the right combination.
Finally, I make a PLAN on paper. Cutting instructions - often with a diagram in crayon. Order of operation, etc. Whatever I need to be successful, I put on that list.
That way, when I start the actual quilting process, all the thinking has been done. All I have to do is pay attention to where I am in the process. It is also nice to check off the steps once completed.
