I started binders containing patterns and fabrics but now just note corrections on patterns and don't bother with anything else except a picture of finished project. I find I REALLY hate trying to do two of the same pattern at the same time or even at a later date.
I had not thought about extra fabric for fixing quilts but am sure as they are gifts, they would be lost or separated by most.
Haven't seen that pattern before but it is beautiful and I wish you luck finding it.
