Artanis, Welcome, and happy this thread is helping not only myself, but hopefully others.
As you are, I am a beginner. I am also in the process of putting together a basic block quilt. Just wish I had had more information and experience when I purchased my first fabric squares. What I have are not uniform, so I will have to adjust the distance in to accommodate those block which are short. I still don't have an accurate way of measuring and cutting, so this is what I have to do. Regardless, the experience is enjoyable.
I hope your foray into quitling will also be an ejoyable, and long lasting one.
