First off, numbers can easily make a task very daunting. I work on one block at a time, especially paper piecing.... Trying to prepare all (1196) at once is overwhelming from the start. I do determine for each block the best way to cut fabric to save it, and I save the (scraps) that may fit into one of the future blocks. When it start the next block I start with the scraps to see if any of them fit into this one. Often when paper piecing I use stash, and keep it (scrappy) to a point. That way, if I run short on one fabric I can easily choose a different one without changing the look/feel of the project. I do, when purchasing fabric for a particular project buy extra, in case I mess up, make a mistake and because I may do something differently than the original was done. If you break this down into manageable sizes ( maybe 2 or 3 blocks at a time ) it may come out much ( happier) than being bogged down/ overwhelmed with trying to keep the whole thing organized
