There are many things to consider when cutting the pieces for a quilt. I prefer that the pattern say I need 400 4 inch squares. I prefer to cut lengthwise borders on the lengthwise grain; therefore, when I cut crosswise pieces to subcut my tally will be different. Also, if I have scraps of that fabric I will try to cut pieces from the scraps before cutting into the bigger pieces. I carefully label all cuts and groups of cut pieces so I don't make silly mistakes as I work. I use plastic bags to store my labeled pieces in. When I have stitched components I put the labels in the upper left corner and use a bigger plastic bag to store them in. I need all the help I can give myself to avoid goofs. I keep lots of notes and reminders as I go.
