I have a large freezer bag that is 14 X 14 and I put all my pieces in there. When I finish a set like 1-6 I staple the instructions so that I know that is complete and then that goes in the bag too. I have several other BOM's that I am doing so I have to keep them separated in plastic bags that are labeled. I had tried cutting out the pieces from one fabric first and then go back and do the other fabric but for some reason two of the blocks had pieces that did not fit and were the wrong size. Thinking I had switched them I looked at teh instructions. NOPE....not one pattern called for the size I had. LOL......must be those darn senior moments creeping in. So I have decided to cut all the pieces for each pattern as I go.
