Yes, Casciamom, it will make a difference, but please don't give up! I suggest that you try making just ONE UNIT following the instructions to see if you like the technique. If you want to try a different technique, check the CLASSROOM link (on the purple bar at the top of the page) to find my videos showing several ways to paper piece the units. If you have cut all of your strips you may be able to salvage the fabric by cutting templates like I show in the video labeled ADD A QUARTER, but you may not have the grain line running the right way. If you have starched your fabric like the instructions tell us to do, and if you are very careful and aware of the possibility of stretching the bias, I think you can salvage most of it.
Also, ARJJ is stocking extra fabric in the TQS Shoppe in case you need to order more.
You can do this!
